SafeBreach Discloses Acer, Asus and Intel Vulnerabilities

====================
[TL DR]
====================
If you have any of the following applications or drivers are installed on your personal systems, please consider updating your drivers using the links below to resolve the reported security vulnerabilities.

In late December a team of security researchers with the security firm SafeBreach published security advisory for Asus, Acer and Intel products that are pre-loaded on many devices from those manufacturers.

Why should these vulnerabilities be considered important?
All of the vulnerabilities could allow an attacker to download a malicious payload, load persistent malware at system start-up and bypass Application Whitelisting and escalate to the highest level of privilege on Windows system namely that of kernel model. These issues are made more serious by the widespread nature of these products.

I later found that my Intel Optane Memory Accelerator fitted to my Intel X299 motherboard is also vulnerable to the Intel RST driver vulnerability.

How can I protect my organisation or myself from these vulnerabilities?
If you use any of the above products, please update them using the download links provided below. Thank you.

Microsoft Guidance for cleaning up orphaned keys generated on vulnerable TPMs (defined) and used for Windows Hello for Business: Security Advisory

Please install the remaining less severe updates at your earliest convenience.

As per standard best 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.

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

Thank you.

====================
Mozilla Firefox
====================
Mozilla released new versions of Firefox to address the following vulnerabilities and to introduce new privacy features:

Firefox 71.0: Resolves 6x high severity CVEs (defined) and 5x moderate CVEs

Firefox ESR 68.3 (Extended Support Release): Resolves 4x high severity CVEs and 4x moderate CVEs

Highlights from version 71 of Firefox include:
An improved password manager which has the ability to recognise subdomains and to provide password breach notifications from Firefox Monitor for users with screen readers. Native MP3 decoding, kiosk mode and picture in picture support were also added.

The tracking protection enabled by default from Firefox 69 has been enhanced to add 3 different levels (similar to high, medium and custom) of protection and to provide a summary of the number of tracking preventative actions Firefox takes on your behalf. An in-depth description of this feature is available in this Softpedia article. My thanks as always to its author Bogdan Popa for this really well gathered information.

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
====================
Google made available two security updates during November; the first resolves 4 vulnerabilities while the second resolves  5 vulnerabilities.

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.

=======================
AMD
=======================
In early December AMD issued a security advisory for its GPU and APU (defined) drivers (defined). It resolves 2 vulnerabilities CVE-2019-5049 and CVE-2019-5098. The steps to install the drivers on Windows are located here with a guide for Linux available here. Please make certain the drivers are version 20.1.1 or later (as per multiple recommendations from Talos, 1 , 2 and 3). As per those same recommendations if you use VMware Player or Workstation Pro, please make certain it is version 15.5.1 or later. If you use the affected AMD graphics cards, please consider updating your drivers to the most recent available.

====================
Nvidia
====================
In late December Nvidia released a security update for Nvidia Geforce Experience to resolve a vulnerability that may lead to a denial of service (defined) issue or an escalation of privilege (defined) issue. This vulnerability is a local vulnerability rather than remote meaning that an attacker would first need to compromise your system before exploiting this vulnerability to elevate their privileges. To resolve this local vulnerability within Geforce Experience  apply the necessary update by opening Geforce Experience which will automatically update it or the update can be obtained from here.

Wireshark
====================
In early December the following Wireshark updates were released:

v3.0.7: 1 security advisory

v2.6.13: 1 security advisory

The above v3.0.7 version was later super seceded by v3.2 on the 18th of December. While it does not address security issues, it will be the version being updated going forward. Version 3.2 will also be the last version to support Windows Server 2008 R2 and Windows 7.

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 (v3.0.7 or v2.6.13). 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.
