May 2018 Update Summary

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

====================
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):

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).

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

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

March 2018 Update Summary

====================
Update: 5th April 2018:
====================
On the 3rd of April, Microsoft released an out of band security update for the Microsoft Malware Protection Protection Engine. Further details are available in this separate blog post.

====================
Separately Microsoft have since issued an update, KB4099950 to resolve the issue detailed below affecting the network adapter on Windows 7.

The new update KB4099950 must be installed before KB4088875 and KB4088878 (I assume if this is not the case that KB4088875 and KB4088878 could be uninstalled first?)

If you were experiencing any of the following issues on Windows 7 or Windows Server 2008 R2, please install the above update to resolve them:

====================
A new Ethernet Network Interface Card (NIC) that has default settings may replace the previous NIC and cause network issues.

Static IP address setting are lost.

These symptoms may occur on both physical computers and virtual machine that are running VMware.
====================

Thank you.

====================
Update: 1st April 2018:
====================
Microsoft have issued an out of band update for Windows 7 SP1 64 bit and Windows Server 2008 R2 SP1 64 bit to resolve resolve a regression (an un-intentional coding error resulting in a previously working software feature no longer working, alternative definition here) which introduced an additional elevation of privilege (defined) security vulnerability in the kernel (defined) of these Windows version, please see my new post for further details.

This post has also been updated with further software releases (please see below).

If you have already checked for updates and are not seeing any being offered for your Windows 7 or Windows 8.1 system, please ensure your anti-malware software is up to date. This article explains why this change was implemented by Microsoft. It also provides recommendations of how to resolve the issue of no updates being available. Windows 10 is not affected by this issue.

A known issue of a second network adapter appearing within Windows 7 has also been documented. If this occurs for you with March’s updates, this news article may be of assistance in resolving it. It is anticipated that Microsoft will resolve this issue in this month’s upcoming security updates.

Thank you.

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)

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
=======================
v2.4.3: 3 CVEs (defined) resolved

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

=======================
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.
  • Firefox ESR 52.5 resolves 3 CVEs.

As always full details of the security issues resolved by these updates are available in the following links:

Firefox 57 and Firefox 57.0.1
Firefox 52.5

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.

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:
=======================

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

November 2016 Security Updates Summary

Earlier today Microsoft and Adobe released their scheduled monthly security updates.

Microsoft’s made available many bulletins, 14 in total. These updates address 67 vulnerabilities listed within Microsoft’s security bulletin summary (as before excluding the Adobe bulletin). These are more formally known as CVEs (defined).

Once again this month (so far) there are no Known Issues detailed within the above mentioned summary page. Monitoring this page before deploying the updates as well as the IT Pro Patch Tuesday blog will keep you well informed enabling you to have the best opportunity to avoid potential issues. If any issues do arise, those pages should be your first places to check for solutions.

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

Today Adobe made available one other security bulletin by Adobe affecting Adobe Connect (resolving 1x priority 3 issue) in addition to their regular Flash Player update. 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 installed automatically alongside the updated version of Google Chrome which was made available very shortly after Adobe’s update.

The Flash Player update addresses 9 priority 1 CVEs. If you use either of these products, please review the security bulletins linked to above and apply the necessary updates.

You can monitor the availability of security updates for the majority of your software from the following websites (among others) or use Secunia PSI:

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 making a donation.

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.

To assist with making the best use of your time when deploying these updates, I will prioritise the updates for you below:

This month the previously disclosed zero day (defined) vulnerability under attacker should take first priority, it is addressed in MS16-135 Next, please prioritise the deployment of the following updates:

Microsoft Internet Explorer, Microsoft Edge, Microsoft Graphics Component , Microsoft Office, Microsoft Video Control and the Windows Security Update bulletin.

Businesses and enterprise should priorities the deployment of the SQL Server update since it addresses 6 important vulnerabilities.

As always Adobe’s Flash Player update (to version 23.0.0.207) should also be on your shortlist this month.

The remaining security updates can be installed when you have the time to do so. Detailed information on the contents of each security bulletin is published each month 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 5.5) 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 is in the process of being retired with the end of support scheduled for the 31st of July 2018.

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.

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.

You can monitor the availability of security updates for the majority of 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.

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.
