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.

====================
A further useful source of update related information is the US Computer Emergency Readiness Team (CERT) (please see the “Information on Security Updates” heading of the “Protecting Your PC” page):

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. Chrome can also be updated immediately by clicking the Options button (it looks like 3 vertically stacked dots) 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.

Adobe has released a further update for Creative Cloud Desktop. I have added the details below to the Adobe updates list.

VMware have also released VMware Fusion 11.5.3 to more completely address a previously patched vulnerability. Details are below in the VMware updates list.

Thank you.

====================
Update: 23rd March 2020
====================

Since originally writing this post, Adobe published their security updates a week later than usual. Further details are listed below.

Thank you.

====================
Adobe
====================
Adobe Acrobat and Reader: 13x Priority 2 CVEs (defined)resolved (9x Critical and 4x Important severity)
Adobe Bridge: 2x Priority 3 CVEs resolved (2x Critical severity)
Adobe ColdFusion:  2x Priority 2 CVEs resolved (2x Critical severity)

====================
Update: 15th March 2020:
====================
Security researcher Kevin Beaumont has provided further details of the critical SMBv3.1 vulnerability affecting Windows 10 Version 1903 and 1909. In summary the vulnerability is not trivial to exploit and the number of systems at the time of writing (13th March) vulnerability to the exploit had already dropped by 25%.

====================
Update: 12th March 2020:
====================
Microsoft have released an update to resolve the SMBv3 vulnerability now designated CVE-2020-0796, (EternalDarkness or SMBGhost) please apply it to any Windows 10 Server or Windows 10 workstation system running Windows 10 Version 1903 or 1909 as soon as possible. Please also make certain that such systems are not exposing port 445 to the internet (please seethe FAQ in their information on the relevant update).

An internet scan by security researchers of vulnerable estimates that there are 48,000 vulnerable Windows 10 systems. You can use the ollypwn scan (created by a Danish security researcher) can be used to check if a system is vulnerable.

I wish to add the following useful clarification (which was written before the Microsoft security update became available) from Richard Melick, senior technical product manager at Automox in relation to this SMBv3 vulnerability:

“Considering that SMBv3 is not as widely used as SMBv1, the potential immediate impact of this threat is most likely lower than past vulnerabilities. But that does not mean organizations should be disregarding any endpoint hardening that can happen now while Microsoft works on a patch…it’s better to respond today and disable SMBv3 and block TCP port 445. Respond now and vulnerabilities end today”.

To all of my readers, please stay safe during these challenging times. Thank you.

====================
Update: 11th March 2020
====================
As expected, yesterday Microsoft  released their scheduled updates to resolve 115 CVEs (defined). Unusually for this month, Adobe has not released any updates.

Microsoft’s monthly summary; lists Known Issues for 14 Microsoft products but all have workarounds or resolution steps listed just as the previous month’s did.

====================
A further useful source of update related information is the 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/

====================
As always for this month’s Microsoft updates, I will prioritize the order of installation below:
====================
For Windows or Windows Server system (Version 1903 and 1909) systems that uses SMBv3, please follow Microsoft’s guidance in the following security advisory while an update is not yet available. Please apply the update as soon as it is made available:

ADV200005 | Microsoft Guidance for Disabling SMBv3 Compression

Please also make certain that TCP port 445 is blocked at the enterprise perimeter firewall to prevent exploitation.

This vulnerability is “wormable” meaning that similar to the WannaCry malware and the BlueKeep vulnerability if exploited it may lead to a very large malware outbreak in a very short time.

Thank you.

=======================
Mozilla Firefox
=======================
In mid-August Mozilla released Firefox 68.0.2 and Firefox ESR 68.0.2 to resolve a moderate information disclosure vulnerability. Please make certain your installation is version 68.0.2 or above to resolve this issue.

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 the above changes.

=======================
Google Chrome
=======================
In late August the Centre for Internet Security released a security advisory for users of Google Chrome to update to version 76.0.3809.132 or later. Prior versions were vulnerable to a use-after-free (defined) vulnerability which could have allowed remote code execution (allowing an attacker to carry out any action of their choice).

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.

=======================
VMware
=======================
VMware earlier this month released a security advisory to resolve 2 Important severity vulnerabilities within the following products:

VMware vSphere ESXi (ESXi)
VMware Workstation Pro / Player (Workstation)
VMware Fusion Pro / Fusion (Fusion)

An attacker could leverage the vulnerability CVE-201-5521 (from the above linked to advisory) to also exploit CVE-2019-5684 to exploit Nvidia’s GPU driver (see below) to gain arbitrary code execution on a system.

If you use the above VMware products particularly with a Nvidia GPU, please review the advisory and apply the necessary updates.

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

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 courtesy of BleepingComputer:
====================

CVE-2018-8267 | Scripting Engine Memory Corruption Vulnerability (a zero day (defined) vulnerability disclosed last month)

Microsoft Edge and Internet Explorer (similar to many other months; multiple versions of Edge and IE affected with many of the CVEs affecting the Microsoft Scripting Engine))

CVE-2018-8225 | Windows DNSAPI Remote Code Execution Vulnerability

CVE-2018-8231 | HTTP Protocol Stack Remote Code Execution Vulnerability (especially if your server hosts a Microsoft IIS installation)

====================
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. I have provided further details of updates available for other commonly used applications below.

Thank you.

Original Post:
=======================
I usually write this post on or very shortly after Update Tuesday (the second Tuesday) of the month but with an Adobe Flash zero day vulnerability (defined) already patched and given that Mozilla have also released an update this month; I felt an earlier post would be appropriate.

I’ll update this post as further updates are made available. Thank you.
