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

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.

October 2017 Security Updates Summary

As scheduled Microsoft released their monthly security updates earlier today. They address 62 vulnerabilities; more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

This month there are 4 Known Issues (kb4041691, kb4042895 , kb4041676 and kb4041681) for this month’s Microsoft updates. 2 of these issues relate to an exception error dialog box appearing, with the others causing a black screen, updates not to install in express , a BSOD and changing of display languages. Microsoft states in each link above they are working on resolutions to these issues.

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

Update: 18th October:

On the 16th of October Adobe released Flash Player v27.0.0.170 to address a critical zero day (defined) vulnerability being exploited in the wild (namely being exploited on computing devices used by the general public in their professional and personal lives)). The BlackOasis APT group are believed to operate in the Middle East. The group is using malicious Microsoft Office documents with embedded ActiveX controls which contain the necessary Flash exploit. This exploit later installs the FinSpy malware.

Please install this update as soon as possible for any device with Flash Player installed. Google Chrome has already automatically received the update while earlier today Windows 8.1 and Windows 10 began receiving it.

As always you can monitor the availability of security updates for most your software from the following websites (among others) or use Secunia PSI:

=======================
Wireshark 2.4.2 and 2.2.10
=======================
v2.4.2: 5 CVEs (defined) resolved

v2.2.10: 3 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 (v2.4.2) or v2.2.10). 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.

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

July 2017 Security Updates Summary

Earlier today as expected Microsoft and Adobe made available their monthly scheduled security updates.

Microsoft resolved a relatively large number of vulnerabilities at 54 in total more formally known as CVEs (defined). However it’s less than last month at 94. These are detailed within Microsoft’s new Security Updates Guide.

After 2 months of updates being released for versions of Windows which were no longer supported, this month is a return to the usual expected patches.

At the time of writing there are no Known Issues for this month’s Microsoft updates. The IT Pro Patch Tuesday blog which I routinely referenced is no longer available.

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

Adobe made available just two security bulletins for the following products:

Adobe Connect (priority 3, 2x important and 1x moderate CVE)

Adobe Flash (priority 1, 1x critical, 2x important 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 (the link includes “April” in the URL but it is not a typo) as appropriate and apply the recommended updates. Google Chrome users should have the updated version installed automatically later this week (if not already available).

If you use any of the above-mentioned Adobe products, please review the security bulletins linked to above and apply the necessary updates. As per the established process 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:

====================
For this month’s Microsoft updates, I will prioritize the order of installation for you below:
====================
Critical severity:

Windows Search

Microsoft Edge and Internet Explorer

NT LAN Manager Elevation of privilege (CVE-2017-8563)(Corporate users: please ensure to set a more secure LDAP setting as per this knowledge base article)

Windows Explorer (CVE-2017-8463)
====================

Please 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 noted in this new blog post, parts of EMET are to become available in the Creator’s Fall Update for Windows 10 set for release in September 2017.

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.

Note: This post marks the 300th post on this blog. Thank you very much to my readers and here’s to the next 300!

=======================
Update:8th August 2017:
=======================

=======================
Nvidia Geforce Drivers:
=======================
This update applies to Linux, FreeBSD, Solaris and Windows and resolves up to 9 security vulnerabilities. The steps to install the drivers are detailed here. I detailed where Nvidia list their security advisories in a previous blog post.

=======================
Putty:
=======================
Putty, the open source and highly popular SSH (defined) client for Windows, was updated to version 0.70 in early July. It contains 1 security fix and 2 non-security bug fixes  (see below).  It is downloadable from here.

=======================
Security fix: the Windows PuTTY binaries should no longer be vulnerable to hijacking by specially named DLLs in the same directory, even a name we missed when we thought we’d fixed this in 0.69. See vuln-indirect-dll-hijack-3.
=======================

If you use Putty, please update it to version 0.70. Thank you.

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. 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 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.

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). This link details how to update your Apple Watch.

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
5. Fix potential out-of-band reads in subtitle decoders and demuxers
6. Fix ADPCM heap corruption (FG-VD-16-067)
7. Fix DVD/LPCM heap corruption (FG-VD-16-090)
8. Fix possible ASF integer overflow
9. Fix MP4 heap buffer overflows
10. Fix Flac metadata integer overflow
11. Fix flac null-pointer dereference
12. Fix vorbis and opus comments integer overflows and leaks
13. The plugins loading will not load external DLLs by default. Plugins will need to LoadLibrary explicitly.

=======================
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.

=======================
GIMP (photo editor):
=======================
The open source ((the source code (human readable code) is free to view and edit by the wider IT community) photo editor GIMP has made available version 2.8.22 which resolves one security vulnerability. If you use this editor, please update it to this version (or later).

Blog Post (Website) Shout Out February 2016

If you are a Nvidia Geforce/Tesla/Tegra/Quadro/Shield owner the following link may be of interest to you. As you may be aware Nvidia regularly make driver (defined) updates for their GPUs (Graphics Processing Units) available to improve performance, add features and fix software bugs.

However, as the link below shows these routine updates also contain fixes for security vulnerabilities e.g. 9 security advisories were issued in 2015 (1 of which affected the Google Android operating system of the Nvidia Shield):

https://www.nvidia.com/object/product-security.html

If you haven’t updated your graphics card driver or Nvidia Shield recently the above website may be worth a visit to obtain and install the most recent security fixes. Further support/information is available from the Nvidia Support page.

Guides for installing drivers on Linux are here and here. Guides for Windows 7/Windows 8 are here with a guide for Windows 10 here.

While I usually provide a respectable shout-out to a blog post I feel this Nvidia website also deserves this for the reasons discussed above.

Thank you.
