July 2020 Update Summary

Earlier this month Adobe and Microsoft made available their expected security updates. These updates resolve 13 and 123 vulnerabilities (respectively) more formally known as CVEs (defined).

An interesting fact as pointed out by ZDI is that for “five straight months of 110+ CVEs released and brings the total for 2020 up to 742. For comparison, Microsoft released patches for 851 CVEs in all of 2019. At this pace, Microsoft will eclipse that number next month. They have already passed their totals for 2017 (665) and 2018 (691)”.

I believe that while this gives us all more work to apply the patches, overall we are becoming safer since more issues are being discovered and resolved.

Let’s begin with Adobe’s updates:

Adobe Bridge: 3x Priority 3 CVEs resolved (3x Critical Severity)

Adobe ColdFusion: 2x Priority 2 CVEs resolved (2x Important Severity)

Adobe Creative Cloud Desktop Application: 4x Priority 2 CVEs (1x Critical and 3x Important Severity)

Adobe Download Manager: 1x Priority 3 (1x Critical Severity)

Adobe Genuine Service: 3x Priority 3 (3x Important Severity)

Adobe Media Encoder: 3x Priority 3 (2x Critical Severity, 1x Important Severity)

Adobe Photoshop: 5x Priority 3 CVEs resolved (5x Critical Severity)

If you use any of the above Adobe products, especially those with critical severity updates; please install these updates as soon as possible.

Microsoft’s monthly summary; lists Known Issues for 11 Microsoft products but all have workarounds or corrective updates.

To all of my readers and your families, I hope you are continuing to stay safe during these tough times; things are slowly getting better. Thank you.

====================
Nvidia
====================
In early July Nvidia released a security update for GeForce Experience. A further security update was released on the 8th of July for Nvidia’s NVIDIA Jetson AGX Xavier, TX1, TX2, and Nano L4T software development kit (SDK) for Linux.

As was the case with previous Nvidia security updates all of these vulnerabilities are local vulnerabilities rather than remote meaning that an attacker would first need to compromise your system before exploiting the vulnerabilities to elevate their privileges.

To resolve the local vulnerabilities within GeForce Experience  apply the necessary update by opening GeForce Experience which will automatically update it or the update can be obtained from here.

An updated version of the Nvidia’s NVIDIA Jetson AGX Xavier, TX1, TX2, and Nano L4T software development kit (SDK) is available from NVIDIA DevZone. An alternative means of mitigating the vulnerability is also provided in the security advisory.

Separately as pointed out above in the update prioritisation for Microsoft’s updates, Nvidia have confirmed that their GPU drivers are not affected by the Windows Hyper-V RemoteFX vGPU vulnerabilities responsibly disclosed by the Cisco Talos team.

====================
Google Chrome
====================
In mid-July Google made available Chrome version 84.0.4147.89 or Linux, Mac and Windows to resolving 38 security vulnerabilities and introducing new features (please the see above Google link for details).

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

Nvidia
=======================
Nvidia late last week issued a related security advisory to that of the above VMware advisory. Nvidia’s advisory resolves 5 locally exploitable vulnerabilities meaning that an attacker would first need to compromise your system before exploiting the vulnerabilities to elevate their privileges (defined). The steps to install the drivers are located here. If you use affected Nvidia graphics cards, please consider updating your drivers (defined) to the most recent available.

=======================
Canon Digital Cameras PTP (Picture Transfer Protocol) Vulnerabilities
=======================
Canon digital cameras utilising this protocol are potentially vulnerable to a complete takeover of the device while connected to a host PC or a hijacked mobile device.

As per this Canon advisory, please ensure your camera is using the most recent firmware update and that you follow the workarounds listed in the above advisory.

=======================
VideoLAN VLC
=======================
On the 19th of August, VideoLAN released VLC version 3.0.8 resolving 13 security issues (some assigned more than one CVE). In a recent presentation their President, Jean-Bapiste Kempf explains the challenges they face in maintaining the security of the project. The short slide deck gives a behind the scenes look at their work including the tools they use to make their code safer.

The list of challenges isn’t too dissimilar from a regular commercial company e.g.: a complex piece of software (15 million lines of code) with approximately 100 dependencies but does highlight issues with hostile bug bounty hunters etc. Future releases will include security bulletins where relevant.

=======================
Valve Steam Gaming Client
=======================
In late August, Valve released 2 security updates for their Steam gaming client. Further information on the disclosure (defined) is detailed here while details of the updates are available here and here (albeit in summary only). The Steam client by default updates automatically. Please open it and allow it to update to resolve these vulnerabilities.

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 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.
