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.

November 2017 Security Updates

Back in November; Microsoft released their routine monthly security updates. These updates resolved 53 vulnerabilities with 14 individual updates (which are grouped when downloaded). As always these are detailed within Microsoft’s new Security Updates Guide.

Sorry for not posting this sooner; travelling for my job meant my time was much more limited.

Microsoft have listed 6 Known Issues that can occur from Windows 7 up to and including Windows 10 (version 1703):

Windows 10 (versions 1511, 1607 and 1703 potentially impacted):

This month there are 4 Known Issues (kb4041691kb4042895 , 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.

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

Adobe also made available their scheduled security updates for the following products:

Adobe Acrobat and Reader (priority 2, 56 CVEs)

Adobe Connect (priority 3, 5 CVEs)

Adobe DNG Converter (priority 3, 1 CVE)

Adobe Digital Editions (priority 3, 6 CVEs)

Adobe Experience Manager (priority 3, 3 CVEs)

Adobe Flash Player (priority 2, 5 CVEs)

Adobe InDesign CC (priority 3, 1 CVE)

Adobe Photoshop CC (priority 3, 2 CVEs)

Adobe Shockwave Player (priority 2, 1 CVE)

As always the priority updates are Flash Player first and Adobe Acrobat (in that order).

One point to note is that Adobe Acrobat 11 (or XI) / Reader 11 are now out of support from November onwards. These will be the final updates they receive. Adobe recommends upgrading to Adobe Acrobat DC or Reader DC (as appropriate). Apart from the different user interface of the DC version, possible privacy concerns were raised about one of the components of this newer version namely RdrCEF.exe (the purpose of which is described here). The suggestions to resolve these concerns were:

  • Adding cloud.adobe.com to your Hosts file (defined) to redirect it to localhost (defined) (to prevent it disclosing any private info)
  • Blocking RdRCEF.exe from accessing the internet using your software firewall

A list of changes to the Windows Registry (defined) were suggested in this forum thread but it is not clear if these are effective.

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

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 Novembers Microsoft updates, I will prioritize the order of installation below:
====================
Critical severity:

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

Microsoft Office Vulnerability : CVE-2017-11882 : was described as “extremely dangerous” by researchers at security firm Embedi to disclosed the vulnerability to Microsoft. In addition to installing the security update they recommend disabling the legacy equation editor to protect against future attackers against the code which does not benefit from the more secure coding practices.

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

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.

Thank you.

=======================
VMware Workstation, Fusion and Horizon View Client
=======================
A security advisory with details of how to obtain updates for the above mentioned products to address 6 CVEs was made available by VMware in November.

=======================
Google Chrome:
=======================
An update for Google Chrome included 2 security fixes while a second update included a further 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 updates to take effect.
=======================

=======================
Wireshark 2.4.3 and 2.2.11

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

=======================
Apple security update:
=======================
An updates was made available by Apple on the 29th of November for macOS High Sierra to resolve a critical security vulnerability that could have resolved in the creation of a root (defined) account on the affected system allowing an unauthorised user privileged access to that system. Further details of this vulnerability are available here. As discussed in that link, this security update should have been installed automatically (no user action required).

=======================
Mozilla Firefox and Firefox ESR
=======================
During November Mozilla released security updates for Firefox and Firefox ESR(Extended Support Release) raising their version numbers to 57 (and later to 57.0.1) and 52.5 respectively.

  • Firefox 57 resolves 15 security issues more formally known as CVEs (defined) while 57.0.1 resolves 2 CVEs.

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.

April 2017 Security Updates Summary

As expected earlier today Microsoft and Adobe released their scheduled monthly security updates.

Microsoft’s set of updates are much lighter in volume this month addressing 45 vulnerabilities more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

This month sees four known issues listed for this months updates all relating to the AMD Carrizo processor experiencing an issue which prevents the installation of future Windows Updates. Microsoft states in all four knowledge base articles (listed below) they are aware of this issue and are working to resolve it in upcoming updates:

KB4015549
KB4015546
KB4015550
KB4015547

At the time of writing the IT Pro Patch Tuesday blog does not list any Known Issues (although it has not been updated since November 2016, I’m unsure why).

====================
Adobe issued five security bulletins today affecting the following products:

Adobe Campaign (1x priority 2 CVE)
Adobe Flash Player (7x priority 1 CVEs)
Adobe Acrobat and Reader (47x priority 2 CVEs)
Adobe Photoshop (2x priority 3 CVEs)

—————
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 Office and Windows WordPad (due to a previously disclosed zero day vulnerability (defined))
Microsoft Edge
Internet Explorer
Microsoft .Net Framework
====================

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 is my standard practice, 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.

February 2016 Security Updates Summary

Since today is the second Tuesday of the month Microsoft and Adobe made available their scheduled security updates for their software.

There are 13 bulletins in total (although MS16-022 is related to Adobe Flash Player) addressing 41 security issues with Microsoft software more formally known as CVEs (defined) and 32 CVEs within Adobe software (22 within Flash Player and a further 10 CVEs in total within Adobe Experience Manager, Adobe Connect and Photoshop CC/Bridge CC):

=======================
Microsoft’s Security Bulletin Summary lists 5 Known Issues with regard to the following bulletins:

MS16-009: Update for Internet Explorer: Knowledge base article kb3134814: After installing this update it can cause websites not to display in Internet Explorer 11 Enterprise mode (used for compatibility with older websites). This issue can be resolved by installing the update documented in knowledge base article kb3141092

MS16-014: Security Update for Windows: Knowledge base articles kb3126587 and kb3126593: Issues include compatibility issues with Corel software (suggested workaround available) and possible error messages appearing in the Windows event log, no workaround provided.

MS16-017: Security Update for Remote Desktop Display Driver: Knowledge base articles kb3134700 and kb3126446: Issues involve needing to restart your computer multiple times after installing this update.
=======================

Microsoft have also made available a security advisory today for ASP.Net templates when used within Visual Studio 2013 and 2015. Users of Visual Studio and/or software developers should review this advisory to determine if you need to take further action.

Moreover; an alternative source for information on Known Issues is the IT Pro Patch Tuesday blog which is usually updated shortly after the release of the updates if any issues are encountered. No issues are listed at the time of writing.

One of Adobe’s updates that was mentioned above addresses 22 critical CVEs within Flash Player. From the many exploits that were developed for Flash Player last year it would be prudent to install this update before any other updates (further discussion provided below). Further details for this update are available in this security bulletin. If you use Adobe Experience Manager, Adobe Connect or Photoshop CC/Bridge CC, please follow the above product links to the appropriate security bulletins and apply the necessary updates.

While the Adobe Flash Player update should be applied before all other updates this month to assist with prioritizing Microsoft’s updates I would recommend beginning to install Microsoft updates starting with the Internet Explorer update, Microsoft Edge, Microsoft Office, Windows PDF Library and Windows Journal (in this order) due to their critical severities and widespread use. You can then install any remaining applicable updates beginning this round of updates with the Kernel Mode Drivers update since exploitation of the vulnerability it addresses is more likely.

One other security pre-caution that you may wish to take if you have Microsoft EMET 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 July’s Update Summary.

As always as a routine precaution I would recommend backing up the data on any device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.
