====================
Mozilla Firefox
====================
On September the 3rd Mozilla released Firefox 69.0 to address the following vulnerabilities and to introduce new privacy features:

Firefox 69.0: Resolves 1x critical CVE (defined), 11x high CVEs, 4x moderate and 3x low CVEs

Firefox ESR 68.1 (Extended Support Release): Resolves 1x critical, 9x high, 4x moderate and 2x low CVEs

Firefox 60.9 ESR : Resolves 1x critical CVE, 7x high CVEs and 1x moderate CVE

Highlights from version 69 of Firefox include:
Blocks 3rd party cookies and cryptominers (using Enhanced Tracking Protection) by default (blocking of fingerprinting scripts will be the default in a future release)

Adobe Flash disabled by default (must be re-enabled if needed)

Separately Mozilla is facing criticism over their plans to gradually roll-out DNS over HTTPS (DoH) later this month since all DNS traffic would go to only one provider, Cloudflare. Google Chrome will implement a similar feature soon (further details are available in the above link also regarding Mozilla).

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.

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

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.

Pwn2Own 2019 Results

TL DR: With popular products such as the Tesla Model 3, Apple Safari, Mozilla Firefox, Oracle VirtualBox, VMware Workstation Pro and Microsoft Edge being successfully exploited; please install the necessary updates when they become available.

The annual white hat hacking contest known as Pwn2Own took place last week. Detailed results from all 3 days are available from this link.

Day 3 saw initially two teams attempting to exploit a Tesla Model 3 before one withdrew. The team Fluoroacetate made up of both Richard Zhu and Amat Cama successfully exploited the infotainment system of the Tesla earning them a further $35,000 and the car itself. They earned $375k in total and became the Master of Pwn for 2019. The contest overall distributed $545k for 19 vulnerabilities.

In contrast to previous years the researchers have targeted vulnerabilities other than those within the operating system kernel (defined) to obtain a total system compromise. Only 3 times were exploits on the OS kernel used this year (one exploit was used in conjunction when exploiting each of the web browsers Apple Safari, Microsoft Edge and Mozilla Firefox).

We can expect updates for each of the exploited products over the coming weeks and months (the vendors have up to 120 days to resolve the vulnerabilities before public disclosure). Mozilla released Firefox 66.0.1 and 60.6.1 to resolve the 2 Firefox CVEs (defined) disclosed during the contest.

If you use the affected products, please keep current with the necessary updates. Thank you.

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:

Intel have released a series of security advisories so far this month. Of highest priority is the advisory for their Intel PROSet/Wireless WiFi Software to resolve a high severity CVSS Base Score 7.8 vulnerability. The security advisory affects many of their WiFi adapters.

Further important updates for their System Support Utility and Intel SGX SDK and Intel SGX Platform Software were also made available. Meanwhile lower severity issues were addressed in Intel’s SSD data-center tool for Windows, Intel NUC Firmware and Intel Optane SSD DC P4800:

If you use any of the affected software or products, please update them as soon as possible especially in the case of the PROSet/Wireless WiFi Software.

December 2018 Update Summary

====================
Update: 3rd January 2019
====================
Apologies for the delay.

Microsoft made available an out of band (un-scheduled) security update available for Internet Explorer on the 19th of December. This vulnerability is being actively exploited; thus if you have not already done, please update your Windows systems. All supported Windows Server and consumer versions of Windows are affected. The full table of affected Windows versions is available here from Microsoft.

For Lenovo laptops running Windows 10 Version 1607 with less than 8 GB of system memory (RAM); Microsoft has provided the following workarounds since this new security update inadvertently causes these systems to be unbootable:

====================
Restart the affected machine using the Unified Extensible Firmware Interface (UEFI). Disable Secure Boot and then restart.

If BitLocker is enabled on your machine, you may have to go through BitLocker recovery after Secure Boot has been disabled.

Microsoft is working with Lenovo and will provide an update in an upcoming release.
====================

Thank you.

====================
Original Post:
====================
Earlier today Microsoft and Adobe made available monthly updates addressing 39 vulnerabilities and 88 vulnerabilities (more formally known as CVEs (defined)) respectively. As always; more information is available from Microsoft’s monthly summary page and Adobe’s blog post.

While Adobe’s update addresses a large number of vulnerabilities; Microsoft’s released updates are fewer in overall vulnerabilities and should be considered light when compared to some months this year. If you use Adobe Flash Player, if you have not already done so; please ensure it is up to date (version 32.0.0.101). They addressed a zero day (defined) vulnerability with that update earlier this month which was in use by an APT group (defined in this context it is an organised group making use of zero day vulnerabilities).

Unfortunately; Microsoft’s updates also come with a list of Known Issues that will be resolved in future updates. They are listed below for your reference:

KB4471318: Windows 7 SP1 and Windows Server 2008 R2 SP1 : Workaround provided

KB4471321 : Windows 10, Version 1607Windows Server 2016 : resolutions are in progress

KB4471324 Windows 10, Version 1803 : resolution in progress

KB4471327 : Windows 10, Version 1703 : resolution in progress

KB4471329 Windows 10, Version 1709 : resolution in progress

As briefly mentioned above Adobe issued updates for Adobe Acrobat and Reader:

Adobe Acrobat and ReaderPriority 2: Resolves 40x Critical CVEs ands 48x Important CVEs

If you use Adobe Acrobat or Reader, please update it as soon as possible especially given the large number of critical vulnerabilities that were patched.

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:

CVE-2018-8611 : Windows Kernel (defined) (this vulnerability is already being exploited)

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

=======================
Mozilla Firefox
=======================
Also earlier today Mozilla made available security updates for Firefox and Firefox ESR (Extended Support Release):

Firefox 64: Resolves 2x critical CVEs (defined), 5x high CVEs, 3x moderate CVEs and 1x low CVE

Firefox ESR 60.4: Resolves 1x critical CVE, 4x high CVEs and 1x low CVE.

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.

Update:
Separately; Firefox 64 now includes small pop-ups known as “snippets” which turned out to be an experiment by Mozilla. If you wish to turn them off; the steps are available here.

Meanwhile extension recommendations within Firefox 64 can be disabled using these steps.

=======================
Google Chrome:
=======================
Google released Google Chrome version 71.0.3578.80 to address 43 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 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.
