May 2018 Update Summary

====================
Update: 5th June 2018:
====================
As discussed in the post below, the zero day vulnerability (defined) designated as CVE-2018-8174 (defined) patched by Microsoft last month has since been incorporated into the RIG exploit kit (defined). The attackers have used the extra detail provided from anti-malware vendors, GitHub (the popular source code repository) and MetaSploit (defined) to create this exploit.

As detailed below, the vulnerability is considered medium severity; however it also requires actions from the user before it take any malicious action usually opening a malicious file or visiting a malicious website.

Please use caution for any email that you receive with an attachment you weren’t expecting. Thank you.

====================
Update: 31st May 2018:
====================
A vulnerability in the JScript (Microsoft’s implementation of JavaScript (defined) has been responsibility disclosed (defined) by Dmitri Kaslov of Telspace Systems, who passed it along to Trend Micro’s Zero-Day Initiative (ZDI). At this time, this vulnerability is un-patched and is thus a zero day vulnerability (defined).

The vulnerability allows a remote attacker to execute malicious instructions of their choice on the victim’s system but only in the context of a sandboxed (defined) environment. In other words, the code cannot itself be used to fully compromise a system. It must be leveraged with another vulnerability to have the potential of fully compromising a system making the vulnerability less serious.

At this time, components within Windows such as wscript.exe and Internet Explorer should not not permitted to run untrusted JScript code. This mitigation (please see the heading near the end of the page named: “How To Tell Explorer To Open .JS Files With Notepad”) may be of assistance with implementing this recommendation.

I will update this post when this vulnerability is patched by Microsoft or when further information becomes available.

Thank you.

====================
Update: 18th May 2018:
====================
Other updates made available by Microsoft for the Spectre Variant 2 vulnerability are:

kb4100347

This update was not offered to my Windows laptop running Version 1803. As you know it contains an Intel Core i7 6500U CPU. I downloaded the version 1803 update from the Microsoft Catalog and it installed successfully. My system is showing the full green result when the PowerShell command Get-SpeculationConntrolSetting is run. It results in the final screenshot shown with this article. Further tips on running this useful command are provided in this Microsoft support article, please see the headings “PowerShell Verification using the PowerShell Gallery (Windows Server 2016 or WMF 5.0/5.1)” or “PowerShell Verification using a download from Technet (earlier operating system versions and earlier WMF versions)” depending on your version of Windows.

Microsoft have also issued an update for Windows version 1709 to resolve a vulnerability again introduced by their previous patch. This resolution was provided in update kb4103727. Further details are available in Alex Ionescu’s tweet (a security architect with CrowdStrike and Windows Internals expert). Previous Spectre V2 patches were kb4091666 and kb4078407

This issue was already addressed in version 1803 of Windows.

If any of the above updates apply for your version of Windows, please install them. If the updates are already present or are not required; the installation will not proceed when you manually attempt it.

Thank you.

====================
Update: 17th May 2018:
====================
Adobe have since issued further updates to resolve critical vulnerabilities within Adobe Acrobat DC, Adobe Reader DC and Photoshop. Further details of the zero day (defined) vulnerabilities addressed in Adobe Acrobat/Reader are available here and here.

Adobe Acrobat and Reader (priority 1, 47 CVEs)

Adobe Photoshop CC 2018 and 2017 (priority 3, 1 CVE).

Further updates are listed at the end of this post. Thank you.

====================
Update: 10th May 2018:
====================
Further details have emerged of another zero day (defined) vulnerability affecting Windows Server 2008 R2 and Windows 7.

CVE-2018-8120 is an elevation of privilege (defined) vulnerability but can only be exploited if the attacker has already compromised the user account of the system allowing the attacker to log in when they choose. Upon logging in the attacker could obtain kernel level access/permissions (defined) by elevating their privileges to carry out any action they choose.

The prioritised list below has been updated to reflect this. Thank you.
====================

====================
Original Post:
====================

====================
Apologies for only posting an update summary last month. Other commitments meant I didn’t have the bandwidth to contribute more. I’ll try to make more time this month. Thanks.
====================

Earlier today Microsoft released their scheduled monthly security updates resolving 67 vulnerabilities. Notably Windows 10 Version 1803 receives it’s first update this month. Windows Server 2016 Version 1803 remains in testing in advance of it’s upcoming release. As always Microsoft have provided further details are provided within their Security Updates Guide.

There are 4 knowledge base articles detailing potential issues (all of which are pending resolutions) you may experience upon installing these updates. They are listed below for your reference:

4103712

4103718

4103723

4103727

====================

Separately, Adobe released updates for 3 of their products, namely:

Adobe Creative Cloud Desktop Application (priority 2 (overall), 3x CVEs)

Adobe Connect (priority 2, 1x CVE)

Adobe Flash Player (priority 2, 1x CVE)

Non-Microsoft browsers should update automatically e.g. Google Chrome should release a browser update in the coming days or will use their component update feature (the update was not available at the time of writing). Like last month; Microsoft issued a security advisory containing details of their updates

As always; you can monitor the availability of security updates for most your software from the following websites (among others) or use one of the utilities presented on this page (since Secunia PSI was phased out on the 20th of April):
—————
US Computer Emergency Readiness Team (CERT) (please see the “Information on Security Updates” heading of the “Protecting Your PC” page):

https://www.us-cert.gov/

A further useful source of update related information is the Calendar of Updates. News/announcements of updates in the categories of General SoftwareSecurity Software and Utilities are available on their website. The news/announcements are very timely and (almost always) contain useful direct download links as well as the changes/improvements made by those updates (where possible).

If you like and use it, please also consider supporting that entirely volunteer run website by donating.

====================
For this month’s Microsoft updates, I will prioritize the order of installation below. A useful list of all CVEs for this month is present here:
====================

Windows VBScript Engine Remote Code Execution Vulnerability (a zero day (defined) vulnerability)

Win32k Elevation of Privilege Vulnerability

Microsoft Edge and Internet Explorer (similar to last month multiple versions of Edge and IE affected with many of the CVEs affecting the Microsoft Scripting Engine))

Microsoft Hyper-V (Update 1 and Update 2)

Microsoft Office (detailed list available here)
====================
Please install the remaining updates at your earliest convenience.

One of the vulnerabilities addressed by Microsoft this month, namely CVE-2081-8897: Windows Kernel Elevation of Privilege Vulnerability arose due to the misinterpretation of documentation from Intel regarding how a CPU (defined) raise a debug (defined) exception to transfer control to debugging software (usually used by a software developer). The specific instructions were the assembly language instructions (defined) MOV to SS and POP to SS.

As usual; I would recommend backing up the data on any device for which you are installing updates to prevent data loss in the rare event that any update causes unexpected issues. I have provided further details of updates available for other commonly used applications below.

Thank you.

=======================
Malwarebytes Anti-Malware
=======================
Last week Malwarebytes updated their anti-malware product to version 3.5.1. The full list of improvements is available here but it also updated their include 7-Zip to version 18.05. I verified this manually since the above release notes did not make reference to it. Further details of the 7-Zip update are available in my April blog post.

Moreover; Directory Opus updated their product to version 12.8.1. Beta adding new DLLs (defined) for 7-Zip and UnRAR once again to address the vulnerabilities found within the UnRAR DLL also used by 7-Zip.

=======================
Mozilla Firefox:
=======================
This month Mozilla made available security updates for Firefox and Firefox ESR (Extended Support Release):

9th May: Firefox 60.0: Resolves 2x critical CVEs, 6x high, 14 moderate CVEs and  4x low severity CVEs

9th May: Firefox ESR 52.8: Resolves 2x critical, 5x high, 3x moderate CVEs

Further details of the security issues resolved by these updates are available in the links above. Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, if you have not already done so, please update it as soon as possible to resolve these security issues.

=======================
Google Chrome:
=======================
Google released Google Chrome version 66.0.3359.170 to address 4 number of vulnerabilities and to include a newer version of Adobe Flash Player.

One of the four vulnerabilities addressed relates to how Chrome handles browser extensions resolving a privilege escalation issue (defined). Further details are availability here.

=======================
Wireshark 2.4.7 and 2.6.1
=======================
v2.4.7: 6 security advisories

v2.6.1: 9 security advisories

As per standard process Linux distributions can obtain this update using the operating systems standard package manager (if the latest version is not installed automatically using the package manager you can instead compile the source code (v2.6.1) or v2.4.7). This forum thread and this forum thread may also be helpful to you with installing Wireshark on your Linux based system.

For Mac OS X and Windows, the update is available within the downloads section of the Wireshark website. In addition, a detailed FAQ for Wireshark is available here.

=======================
USB Denial of Service (DoS) Will not Receive a Fix
=======================
In other vulnerability related news; a denial of service issue (defined) privately/responsibly disclosed (defined) by a security researcher Marius Tivadar will not fixed by Microsoft with a security update since the vulnerability requires physical access to the target system or social engineering (defined) and does not result an attacker being able to execute code of their choice on the affected system.

In my opinion; this is justified since if an attacker can obtain physical access to your system it significantly enhances the damage they can do. This statement also forms part of Microsoft’s 10 Immutable Laws of Security.

====================
Update: 31st May 2018
====================

=======================
VideoLAN VLC:
=======================
Yesterday VideoLAN made available VLC version 3.0.3 for Linux, Windows, macOS, BSD, Android, iOS, UWP and Windows Phone. It’s release notes detail one potential security issue (buffer overread  (defined)) and other 3rd party libraries being updated to address security issues. No specific numbers were provided. A large number of non-security issues were also resolved.

Please update to version 3.0.3 to benefit from these improvements.

=======================
Google Chrome:
=======================
Earlier this month Google made available version  67 delivering 34 security issues. The improvements part of this new version are discussed in this Bleeping Computer article.

Moreover this version includes an early implementation of a new user interface for the tabs, address bar, settings button (sometimes referred to as the “chrome” (no pun intended) of an application). This article provides more details and includes steps to enable the new UI. I have done so and it’s a subtle difference but I already really like it. The Incognito mode is even more noticeable. The UI also seems more responsive (but that may be placebo effect).

Google Chrome updates automatically and will apply the update the next time Chrome is closed and then re-opened. Chrome can also be updated immediately by clicking the Options button (it looks like 3 stacked small horizontal lines, sometimes called a “hamburger” button) in the upper right corner of the window and choosing “About Google Chrome” from the menu. Follow the prompt to Re-launch Chrome for the updates to take effect.
=======================

=======================
Apple Security Updates:
=======================
In late May Apple made available the following updates. Interestingly while the updates were available; no specific details of the improvements they include (security or otherwise) are yet available.

Initially, further details of the updates made available by Apple are emerging. Sophos have theroized that Apple have made improvements to the iOS Messages app making it more stable and less susceptible to crashing. They are thus recommending that you install the iOS 11.4 update as soon as possible.

They also discuss the addition of a new security feature which blocks access to a mobile device if the passcode has not been entered within the last seven days. This change is expected to become part of 11.4.1 and a stricter form for iOS 12. After this time the Apple Lightning cable will only charge the device and not allow data access. This appears to be part of Apple’s response to law enforcement and forensics firms accessing Apple devices attempting to collect evidence of the device’s owner’s wrongdoings.

Further details have since emerged for these Apple security updates:

Apple iOS v11.4 (resolves 35x CVEs (defined))

Apple tvOS 11.4 (resolves 24x CVEs)

Apple watchOS 4.3.1 (resolves 20x CVEs)

Apple iTunes version 12.7.5 for Windows (resolves 16x CVEs)

Moreover, BleepingComputer have discussed two of the vulnerabilities patched were buffer overflows (defined) both present in the kernels (defined) of iOS, macOS, tvOS and watchOS.

=======================

Please see these links from Apple for advice on backing up your iPhone and iPad. Advice for updating tvOS is available here while the steps for updating the Apple Watch are available here.

As always; further details of these updates are available on Apple’s dedicated security updates page.

For advice on how to install updates for Apple devices, please see the steps detailed at the end of this Sophos blog post as well as this link (from my “Protecting Your PC” page).

=======================
Hitman Pro:
=======================
As recommended on my Tools and Resources page, Hitman Pro (now part of Sophos Security) has been updated to version 3.8.20 (Build 294). This update resolves a vulnerability relating to DLL hijacking (defined)(apologies; for this link you may need to dismiss several adverts before the requested page loads). Any previous version of the tool should update automatically when opened to the most recent version.

January 2018 Update Summary

====================
For January’s Microsoft updates, I will prioritize the order of installation below. I will discuss this month’s out of band (outside of the regular schedule) patches for Meltdown and Spectre in a separate blog post; the relevant CVEs are still listed below. A useful list of all CVEs for this month is present here:

====================
CVE-2017-5753 – Bounds check bypass (known as Spectre Variant 1)

CVE-2017-5715 – Branch target injection (known as Spectre Variant 2)

CVE-2017-5754 – Rogue data cache load (known as Meltdown Variant 3)

Microsoft Office (18 further CVEs)

Microsoft Edge and Internet Explorer (multiple versions of Edge and IE affected)

====================

Please install the remaining updates at your earliest convenience.

As usual; I would recommend backing up the data on any device for which you are installing updates to prevent data loss in the rare event that any update causes unexpected issues.

For this month; please take extra care with your back up to ensure you can restore your systems should you wish to revert your systems prior to installing the Meltdown and Spectre patches should you wish to uninstall the Security only bundle of updates or the updates are causing your system to become unstable.

Thank you.

=======================
Wireshark 2.4.4 and 2.2.12
=======================
v2.4.4: 3 CVEs (defined) resolved

v2.2.12: 4 CVEs resolved

As per standard process Linux distributions can obtain this update using the operating systems standard package manager (if the latest version is not installed automatically using the package manager you can instead compile the source code (v2.4.4) or v2.2.12). This forum thread and this forum thread may also be helpful to you with installing Wireshark on your Linux based system.

For Mac OS X and Windows, the update is available within the downloads section of the Wireshark website. In addition, a detailed FAQ for Wireshark is available here.

====================
Update: 24th January:
====================
Oracle:
====================
Oracle have resolved 237 vulnerabilities with the security updates they have made available this month. Further details and installation steps are available here. Within the 237 vulnerabilities addressed, 21 vulnerabilities were addressed in the Java runtime. 18 of these 21 are remotely exploitable without an attacker needing to obtain a user’s username and password (their credentials).

If you use any of the Oracle products listed here, please install the appropriate security updates as soon as possible.

Particular priority should be given to Oracle WebLogic Server and PeopleSoft due to documented incidents of attackers using such installations for crypto currency mining with one such incident resulting in more than USD $226,000 being mined. Further details are available in the following blog post from security vendor Onapsis.
=======================

=======================
Further updates released in January:
=======================
VMware Updates:
=======================
In early January; VMware issued security updates to address the Meltdown and Spectre vulnerabilities within some of their products. Another advisory  was also released later in January. The affected products/appliances are listed below. For virtual machines used with VMware Fusion and VMware Workstation, the steps listed within this knowledge base article should also be followed.

Please review the above linked to security advisories and knowledge base article and apply the necessary updates and mitigation steps.

Affected products/appliances:

  • VMware vCenter Server (VC)
  • VMware vSphere ESXi (ESXi)
  • VMware Workstation Pro / Player (Workstation)
  • VMware Fusion Pro / Fusion (Fusion)

=======================
Mozilla Firefox:
=======================
In January Mozilla issued security updates for Firefox and Firefox ESR (Extended Support Release):

Firefox 57.0.4 (2 mitigations added)

Firefox 58: 3x critical, 13x high, 13x moderate, 2x low CVEs

Firefox 58.0.1: 1x critical CVE

Firefox ESR 52.6: 1 high CVE

Firefox ESR 52.6: 2x critical, 8x high, 1x moderate

Further details of the security issues resolved by these updates are available in the links above. Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, if you have not already done so, please update it as soon as possible to resolve these security issues.

=======================
Google Chrome:
=======================
In late January an update for Google Chrome was made available which included 53 security fixes.

Google Chrome updates automatically and will apply the update the next time Chrome is closed and then re-opened. Chrome can also be updated immediately by clicking the Options button (it looks like 3 stacked small horizontal lines, sometimes called a “hamburger” button) in the upper right corner of the window and choosing “About Google Chrome” from the menu. Follow the prompt to Re-launch Chrome for the updates to take effect.

=======================
7-Zip
=======================
In late January a security researcher located 2 vulnerabilities within 7-Zip. He reported them to the developer Igor Pavlov who very quickly released an updated version; v18.00 Beta. This has since been updated to 18.01 Stable to fix further issues (NOT security related).

The alternative Windows file manager Directory Opus will include the updated 7-Zip DLL (defined) within their next release. Their current beta already contains these fixes.

While 7-Zip does not have many vulnerabilities discovered within it (which has both advantages and disadvantages), there appears to be an increasing emphasis on it since it is used by anti-malware software and other applications e.g. VMware Workstation. Thus when a security update is issued; all of this software should eventually include the fixes. This occurred last year with the release of 7-Zip 16.00 to resolve 2 other security vulnerabilities.

Separately, Malwarebytes updated their Anti-Malware product to version 3.4.4 to update the 7-Zip DLL (defined) within it. Further details are available in my March 2018 Update Summary blog post.

If you use 7-Zip, please ensure it is updated to resolve both this year’s vulnerabilities and last year’s vulnerabilities (if you hadn’t already installed version 16 or later). Please also update Malwarebytes Anti-Malware or Directory Opus if you use them.

=======================
Nvidia Geforce Drivers:
=======================
This driver update applies to Linux, FreeBSD, Solaris and Windows and mitigates the Meltdown security vulnerability (CVE-2017-5753). While Nvidia’s GPUs are not vulnerable to Meltdown or Spectre, the GPUs interaction with an affected CPU has the potential for exploitation.The steps to install the drivers are detailed here. I detailed where Nvidia list their security advisories in a previous blog post. More details about the Meltdown and Spectre vulnerabilities are available in this blog post.

=======================
Hitman Pro:
=======================
As recommended on my Tools and Resources page, Hitman Pro (now part of Sophos Security) has been updated to version 3.8.20 (Build 292). This update resolves 2 vulnerabilities relating to libraries (defined) the tool uses namely zlib and libpng. Any previous version of the tool should update automatically when opened to the most recent version.

May 2017 Security Updates Summary

Today Microsoft and Adobe made available their expected monthly security updates.

Microsoft’s updates address 57 vulnerabilities more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

At the time of writing there are no Known Issues for this month’s Microsoft updates. The IT Pro Patch Tuesday blog while not updated since last month doesn’t contain this months updates yet.
====================

Before continuing with this months updates I wanted to provide information on a critical out of band (un-scheduled) update made available by Microsoft yesterday to address a vulnerability responsibly disclosed (defined) by Google Project Zero researchers Natalie Silvanovich and Tavis Ormandy within Microsoft’s Malware Protection Engine. The full list of affected products is listed within their security advisory. The exploit code for this vulnerability was later published within a tweet (which will not exploit the vulnerability).

I recommend updating your version of the Malware Protection Engine as soon as possible to version 1.1.13704.0 (or later) since this vulnerability when exploited by an attacker will lead to them obtaining system level access (NT AUTHORITY\SYSTEM)(defined)(namely the highest level of privilege within a Windows system) over an affected system.

====================
Also today Adobe issued two security bulletins for the following products:

Adobe Experience Manager Forms (1x priority 2 CVE)
Adobe Flash Player (7x priority 1 CVEs)

The priority ratings are explained in this link. Depending on which version of Flash Player you have, please review the Adobe security bulletin or Microsoft bulletin as appropriate and apply the recommended updates. Google Chrome users will have the updated version installed automatically later this week.

If you use any of the above-mentioned Adobe products, please review the security bulletins linked to above and apply the necessary updates. As always the Flash update should be installed as soon as possible since exploit kits (defined) tend to take advantage of newly disclosed vulnerabilities very quickly.

You can monitor the availability of security updates for most your software from the following websites (among others) or use Secunia PSI:
—————
US Computer Emergency Readiness Team (CERT) (please see the “Information on Security Updates” heading of the “Protecting Your PC” page):

https://www.us-cert.gov/

A further useful source of update related information is the Calendar of Updates. News/announcements of updates in the categories of General Software, Security Software and Utilities are available on their website. The news/announcements are very timely and (almost always) contain useful direct download links as well as the changes/improvements made by those updates (where possible).

If you like and use it, please also consider supporting that entirely volunteer run website by donating.

—————
If you use any of the above software, please install the appropriate updates as soon as possible. Steps for installing updates for Windows are provided on the “Protecting Your PC” page.

====================
For the Microsoft updates this month, I will prioritize the order of installation for you below:
====================
Critical severity:
Microsoft Malware Protection Engine
Microsoft Office
Microsoft Edge
Internet Explorer
Microsoft SMB (CVE-2017-0277, CVE-2017-0278, CVE-2017-0279)
====================

Install the remaining updates at your earliest convenience.

As always you can find detailed information on the contents of each security bulletin within ComputerWorld’s Patch Tuesday Debugged column.

Another security pre-caution that you may wish to take if you have Microsoft EMET (please ensure your version of EMET is the most recent version 5.52) installed is to use it to protect you from Adobe Flash being used to exploit vulnerabilities when you open a Microsoft Office document or Adobe PDF file. I provide recommendations of how to do this at the end of the July 2015 Update Summary. Please note that Microsoft EMET will be out of support on the 31st of July 2018.

As usual; I would recommend backing up the data on any device for which you are installing updates to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.

=======================
Update: 10th May 2017:
=======================
I wish to provide information on other notable updates from May 2017 which I would recommend you install if you use these software products. I only choose a small number of products to list here since it can easily become too many and I wish to highlight the security benefits of installing the latest version of applications many of us use everyday:

=======================
Mozilla Firefox:
=======================
Firefox 53.0.2

=======================
Mozilla Firefox ESR:
=======================
Firefox ESR 52.1.1

Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, please update it as soon as possible to resolve these security issues.

=======================
Google Chrome:
=======================
Google Chrome: includes 1 security fix.

Google Chrome updates automatically and will apply the update the next time Chrome is closed and then re-opened.

Follow the prompt to Re-launch Chrome for the update to take effect.
=======================

=======================
Nvidia Geforce Drivers:
=======================
This update applies to Linux, FreeBSD, Solaris and Windows and resolves up to 15 security vulnerabilities. The steps to install the drivers are detailed here.

I detailed where Nvidia list their security advisories in a previous blog post.

=======================
Malwarebytes:
=======================
This update to Malwarebytes 3.1 (specifically v3.1.2.1733) resolves more than 1 security vulnerability (exact numbers and further details are not available).

Malwarebytes typically roll out updates in waves meaning it may be sometime before you receive this update. If the update is not automatically downloaded and installed in a timely manner, it is available from this link. Manual installation and general troubleshooting steps are available here.

=======================
Apple security updates:
=======================
Updates were made available by Apple on the 15th of May for iTunes for Windows, Safari, macOS Sierra, El Capitan and Yosemite, iOS, watchOS, tvOS, and iCloud for Windows.

Please see these links from Apple for advice on backing up your iPhone and iPad. Advice for updating tvOS is available here.

Further information on the content of these updates is available this blog post.

=======================
Hitman Pro:
=======================
As recommended on my Tools and Resources page, Hitman Pro (now part of Sophos Security) has been updated to version 3.7.20 (Build 286). This update resolves 3 important vulnerabilities relating to the driver the tool uses for scanning. Any previous version of the tool should update automatically when opened to the most recent version.

=======================
VideoLAN VLC:
=======================
=======================
Update: 25th May 2017:
=======================
Yesterday VideoLAN released version 2.2.6 of VLC for Windows only. It resolves the security issues listed below (assuming at least 2 heap overflows (given their use of the plural form)). This list came from the NEWS.txt file after installing version 2.2.6 since the detailed release notes on VideoLAN’s website have not yet been updated (and may not be until 2.2.6 is officially made available for macOS and Linux systems).

The update is currently being distributed via their automatic updater (upon opening VLC) and manually from their website (unexpectedly that page also contains tarballs for Linux):

Changes between 2.2.5.1 and 2.2.6:
———————————-

Video output:
* Fix systematic green line on nvidia
* Fix direct3d SPU texture offsets handling

Demuxer:
* Fix heap buffer overflows

———————————-

It was not known at the time version 2.2.5.1 was made available that the correction of “Fix potential out-of-band reads in subtitle decoders and demuxers” were actually security issues assigned to 4x CVEs discovered by CheckPoint security.

=================
Late last week VideoLAN released version 2.2.5.1 of VLC. This update is available for Linux, Apple Mac OS X and Windows. It addresses (at least) 13 security issues mentioned here (I’ll explain my numbering using the list below). This update is available for download for the above operating systems from this page.

If you use VLC, please update as soon as possible to address the above mentioned security vulnerabilities as well as the general software bugs that were resolved.

1. Security hardening for DLL hijacking environments
2. Fix potential out-of-band dereference in flac decoder
3. Fix potential out-of-band reads in mpeg packetizers
4. Fix incorrect memory free in ogg demuxer

Notepad++:
=======================
On the 14th of May, Notepad++ made available a new version updating it to version 7.4. While it is not a security update it includes a security related improvement namely: Improve certificate verifying method.

This version has since been updated to version 7.4.1 to resolve a number of non-security issues. If you use Notepad++, please consider updating to the most recent version to benefit from the security improvement and the bug fixes it includes.

Please note, the 64 bit version of Notepad++ became available in September 2016. It allows the opening of larger files and includes High Entropy ASLR (Address Space Layout Randomization (defined)) on a 64 bit version of Windows. I have discussed HEASLR on this blog before and it’s an excellent security measure/control/mitigation (defined). Further information on HEASLR can be found on Alex Ionescu’s blog.
