February 2019 Update Summary

Earlier today Microsoft made available 13 bulletins and 3 advisories resolving 74 vulnerabilities (more formally known as CVEs (defined)) respectively. As always more details are available from Microsoft’s monthly summary page.

Also today Adobe released scheduled updates for the products listed below addressing 75 CVEs in total:

Adobe Acrobat and Reader: 71x priority 2 CVEs resolved (43 of the 75 are Critical, the remainder are Important severity)

Adobe ColdFusion: 2x priority 2 CVEs resolved

Thank you.

=======================
Nvidia Graphics Drivers:
=======================
8 security vulnerabilities with the most severe having a CVSS V3 (defined) base score of 8.8 have been resolved within Nvidia’s graphics card drivers (defined) in February. These vulnerabilities affect Linux FreeBSD, Solaris and Windows. The steps to install the drivers are detailed here (and here) for Ubuntu and here for Linux Mint. Windows install steps are located here. If you use affected Nvidia graphics card, please consider updating your drivers to the most recent available.

=======================
7-Zip:
=======================
In the 3rd week of February; 7-Zip version 19.00 was released. While it is not designated as a security update; the changes it contains appear to be security related. While 7-Zip is extremely popular as a standalone application; other software such as Malwarebytes Anti-Malware, VMware Workstation and Directory Opus (among many others) all make use of 7-Zip. Directory Opus version 12.2.2 Beta includes version 19.00 of the 7-Zip DLL.

If you use these software applications or 7-Zip by itself, please update these installed applications to benefit from these improvements.

=======================
Changes:
=======================
– Encryption strength for 7z archives was increased:
the size of random initialization vector was increased from 64-bit to 128-bit, and the pseudo-random number generator was improved.
– Some bugs were fixed.
=======================

If you are using the standalone version and it’s older than version 19, please consider updating it.

=======================
Mozilla Firefox
=======================
In mid-February Mozilla issued updates for Firefox 65 and Firefox ESR (Extended Support Release) 60.5:

As always; 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 benefit from changes such as improvements to Netflix playback, color management on Apple macOS and resolving audio/video delays during WebRTC calls etc.

=======================
Wireshark 3.0.0, 2.6.7 and 2.4.13
=======================
v3.0.0: 0 security advisories (new features and benefits discussed here and here)

v2.6.7: 3 security advisories

v2.4.13: 3 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 (v3.0.0, v2.6.6 or v2.4.12). 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.

Note: from this post onwards, I will only report on the most recent (v3.0) and previous branches (v2.6) of Wireshark.

Thank you.

January 2019 Update Summary

====================
Updated: 9th January 2019
====================
Happy New Year to all of my readers. Thanks very much.

Today Microsoft made available monthly updates resolving 47 vulnerabilities (more formally known as CVEs (defined)) respectively. Further details are available from Microsoft’s monthly summary page.

Separately Adobe released out of band (unscheduled) updates last week for Acrobat 2017 and Acrobat DC/Acrobat DC. These updates address 2x critical CVEs.

Other updates released today are as follows:
Adobe Connect: 1x priority 3 CVE resolved
Adobe Digital Editions: 1x priority 3 CVE resolved
Adobe Flash Player: reliability/performance update only

While the Flash Player update is a non-security update it’s likely Adobe chose to release it via the usual channels since it’s what people are familiar with and it helps to get updates out sooner.

Similar to last month; Microsoft’s updates come with a long list of Known Issues that will be resolved in future updates. They are listed below for your reference:

Microsoft Issues Windows Defender Security Update: 3rd April

On April 3rd, Microsoft issued an out-of-band (outside of their usual schedule of the second Tuesday of the month) update to address a critical vulnerability within the Microsoft Malware Protection Engine (part of Windows Defender, Microsoft Security Essentials, Windows Intune Endpoint Protection, Exchanger Server 2013 and 2016 and Microsoft Forefront Endpoint Protection 2010).

Since these anti-malware applications are designed to automatically update; they should install the updated Malware Protection Engine within 48 hours.

If you wish to verify that your installation of these products has been updated, please follow the steps within this knowledge base article (please see the heading “Verification of the update installation”).

The updated Malware Protection Engine version is 1.1.14700.5 (or a later/higher version). Thank you.

March 2017 Security Updates Summary

As you know Microsoft and Adobe released their scheduled monthly security updates. For Microsoft this release was anticipated especially since last month’s set was delayed.

Within the above linked to post I predicted Microsoft would make a large number of updates and they did just that. 17 bulletins in total are now available. These updates address 138 vulnerabilities listed within Microsoft’s new Security Update Guide. These vulnerabilities are more formally known as CVEs (defined).

Once again; there are no Known Issues listed within their March summary page. At the time of writing the IT Pro Patch Tuesday blog does not list any Known Issues. However, please check it before deploying your security updates just to be sure. As always, if any issues do arise, those pages should be your first places to check for solutions.
====================

Adobe issued two security bulletins today. One affecting Adobe Flash and the other for Adobe Shockwave Player. The Flash Player bulletin resolves 8x priority 1 vulnerabilities. While the Shockwave bulletin resolves 1x priority 2 vulnerability. These priority rating are explained in the previous 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 installed automatically alongside the updated version of Google Chrome which was made available last week.

If you use Flash or Adobe Shockwave, please review the security bulletins linked to above and apply the necessary updates. 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:

=======================
Update: 22nd March 2017:
=======================
I wish to provide information on other notable updates from this month which I would recommend you install if you use these software products:

Notepad++ version 7.3.3

VideoLAN VLC Media version 2.2.5 (release currently in progress)

Malwarebytes Anti-malware version 3.0.6 CU3 (with Component package version: 1.0.75):
It is unknown how many vulnerabilities this addresses but this forum post mentions their resolution.

Malwarebytes Anti-malware version 3.0.6 CU4 addresses further vulnerabilities.

More details of the vulnerabilities resolved by Malwarebytes 3.0.6 CU3 have emerged. Researchers responsibly disclosed a technique which uses Microsoft’s Application Verifier to hijack an anti-malware application. More details of this vulnerability are available here and here.

Mozilla Firefox 52.0.1 (more details in this post on Pwn2Own 2017)

VMware Workstation 12.5.4 (relevant security advisories are here and here)

VMware ESXi, Fusion and VMware Workstation 12.5.5 (the relevant security advisory is here). This advisory resolves the vulnerabilities disclosed during Pwn2Own 2017 for the above listed products.

Wireshark 2.2.5 and 2.0.11

Putty 0.68 (while released in February; it contains important security changes)

Apple Security Updates: updates are available for iTunes, iTunes for Windows, Pages, Numbers, Keynote (for macOS and iOS), Safari, macOS Sierra, El Capitan and Yosemite, iOS, watchOS, tvOS, macOS Server, 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.

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

For the 17 Microsoft bulletins this month, I will prioritize the order of updates for you below:

====================
Critical severity:
Windows Graphics Component

Windows SMB Server

Microsoft Edge

Internet Explorer

Windows Hyper-V

Windows PDF

====================
Important Severity
====================
The update for Microsoft Office should be installed next due to it’s criticality. With the follow updates after it:

Microsoft Exchange

Microsoft IIS

Active Directory Federation Server

As always you can find 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 5.52) 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.

September 2016 Security Updates Summary

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

Microsoft’s updates consist of 14 security bulletins. These bulletins address 50 vulnerabilities more formally known as CVEs (defined)(not including the Adobe vulnerabilities mentioned below).

Only the Internet Explorer security bulletin currently lists a Known Issue (discussed below). However as always please double check the IT Pro Patch Tuesday blog to ensure that there are no issues being experienced before you begin installing the new updates. At this time it does not list any Known Issues.

Update: 15th September 2016:

It has been reported that the security updates for Internet Explorer MS16-104 and Microsoft Edge (MS16-105) patches a zero-day (defined) vulnerability that has been publicly exploited. Further details of this vulnerability have since been disclosed and are available in this ThreatPost article.

The Known Issue for this update now mentions “Microsoft is aware of limited issues in which an ActiveX install may fail when using the ActiveX Installer Service (AXIS) with Internet Explorer 10 or Internet Explorer 11.” However, at this time no workaround or solution is available.

Moreover, the Microsoft Office security bulletin resolves an Important severity level ASLR (defined) bypass designated CVE-2016-0137 within the Microsoft Detours DLL (defined) that applications such as Microsoft App-V use. This issue has the potential to affect a lot of other 3rd party products and is discussed in more detail in this ThreatPost article. Further information/resources concerning this vulnerability are available on this GitHub page. A possibly related issue was found in Nvidia’s graphics driver (defined) (within detoured.dll) late last year which they issued a patch for.

This month also marks the final month that Windows 7 and Windows 8.1 will receive security updates packaged in the traditional format. From October the updates will be offered in packages similar to that of Windows 10 which will mean fewer individual updates will need to be installed to bring systems up to date. The updates will also replace updates from previous months again reducing the volume of updates needing to be installed. There will be single security and reliability updates.

While I am in favour of the simplification of updates, the “Known Issues” that I mention each month will become even more important since you won’t have the option of choosing which updates to install. This will lead to more outages and compatibility issues especially for corporate environments which is discussed in this article. Microsoft provides more details of these changes in their Windows IT Pro blog post. This additional Microsoft blog post and this Windows IT Pro blog post provide further coverage.

Further to this, next month Microsoft plans to begin to block out dated versions of Adobe Flash Player ActiveX controls (defined). Further details are available in their blog post.

====================
For Adobe’s scheduled released they made available an updated version of Flash Player that addresses 29 priority 1 vulnerabilities.

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 released today.

Adobe also released a security bulletin for Adobe AIR SDK and compiler (AIR is its application runtime) to address a single priority 3 vulnerability. More information as well as installation steps are available in the relevant security bulletin. Finally, Adobe released a security bulletin for Digital Editions that addresses 8 priority 3 vulnerabilities.

If you use any 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:

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:

With Adobe’s Flash Player update (to version 23.0.0.162) addressing 29 critical vulnerabilities, this should be installed first if you already have a previous version installed.

For the Microsoft updates, for corporate environments/server operating systems please first install the Microsoft Exchange update (if you use it within your environment). This should be followed by Microsoft Office, Security Update for Windows (MS16-110) and the Microsoft Graphics Component.

For desktop workstations / small business environments please make Internet Explorer, Microsoft Edge, Microsoft Office and the Microsoft Graphics Component your first priorities due to their severities and prevalent use. 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 available in this Computerworld article (a new article is published each month within their 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.

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.
