Thank you.

====================
Mozilla Firefox
====================
Earlier this month Mozilla released Firefox 73 and Firefox ESR  (Extended Support Release) 68.5 to address the following vulnerabilities:

Firefox 73.0: Resolves 3x high severity CVEs and 3x moderate severity CVEs

Firefox ESR 68.5: Resolves 2x high severity CVEs and 3x moderate severity CVEs

Firefox 73 brings the following minor features listed below:

  1. A global zoom level configured from the settings menu
  2. Opt-in notification when the use of virtual reality is being requested
  3. A new DNS over HTTP (DoH) (defined) provider was added within Firefox. The new provider, NextDNS can be selected as follows: Select Options -> General -> Network Settings. Scroll down and place a tick/check in the ‘Enable DNS over HTTPs’ box and finally choose from NextDNS as a DoH provider.

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 a security update in early February; resolving 56 vulnerabilities bringing Google Chrome to version 80. A further 2 updates on the 11th and 13th were also released but are not security updates.

Version 80 of Chrome also brings changes to how it handles cookies (defined). Specifically, restricting them to first party access by default and requiring website developers to specify within their code which cookies are allowed to work across websites. In addition, 3rd party cookies will then only be sent over HTTPS. This change was initially announced by Google in May 2019. As Google states “This change also has a significant security benefit for users, protecting cookies from cross-site injection and data disclosure attacks like Spectre and CSRF by default”. Further advice to developers is available in this video.

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.

====================
Realtek Audio/Sound Card Drivers
====================
In early February, the hardware manufacturer Realtek released an updated audio/sound card driver. This driver addressed a security vulnerability that requires an attacker to have already compromised your Windows system and to have obtained administrative privileges. More information on this vulnerability is available from the security researchers who responsibly disclosed (defined) it to Realtek. The vulnerability has been assigned CVE-2019-19705 by Mitre.

This vulnerability is a DLL search-order hijacking vulnerability (defined) which if exploited could allow an attacker to download and run a malicious executable file on your system. They also have the ability to achieve persistence on your system namely that any malware they install will remain on your system after it is shutdown or restarted.

If your system uses a Realtek audio device (use Windows Device Manager and expand the category named “Sound, video and game controllers” looking for a device with Realtek in its name), please refer to the manufacturer of your desktop, laptop or motherboard for a driver update. If no driver is available, please contact them to request that a driver be made available. As per Realtek’s security advisory, drivers with versions later than 1.0.0.8856 (legacy , non DCH (what is the difference between DCH and standard drivers?) are not vulnerable.

January 2020 Update Summary

====================
Update: 11th February 2020
====================
This Internet Explorer zero day (defined) vulnerability was resolved by the patch released by Microsoft today. If you use Internet Explorer (especially versions 8 or earlier), please install this update as soon as possible.

Thank you.

==============
Update: 27th January 2020
==============
Shortly after the release of Microsoft’s scheduled updates, on the 17th of January they issued a security advisory for a critical zero day (defined) vulnerability being exploited by attackers in targeted attacks.

An out of bound update has not been released by Microsoft since by default all support versions of Internet Explorer by default use Jscript9.dll rather than Jscript.dll However versions earlier then IE 9 face increased risk.

If you use Internet Explorer for day to day work or just general surfing, please consider implementing the workaround described within Microsoft’s security advisory. Please remember to remove the workaround prior to installing the relevant security update in February. Also, please note that this workaround is causing some printers not to print and the Microsoft Print To PDF function not to work. If this is the case, use another browser and disable the workaround or use the micropatch (discussed below).

An alternative which according to ghacks.net is free is to install the micro-patch for IE available from 0Patch. More information on the micropatch and how to install it is available in the previous link above. This micropatch does not come with side effects. A YouTube video of the micropatch in action is available from the following link:

https://youtu.be/ixpBN_a2cHQ

Thank you.

====================
Microsoft Edge Chromium
====================
Tomorrow, 15th January will mark the release of a new version of Microsoft Edge powered by the Chromium rendering engine. This version will be available for Windows 7, 8.1 and 10. This is especially relevant for Windows 7, Windows Server 2008 and Server 2008 R2 since while Windows itself ends its support lifecycle today, Edge Chromium will continue to be supported for a further 18 months. This matches similar statements from Google regarding Chrome and separately Vivaldi.

For details of which versions of Windows 10 will receive the new Edge via Windows Update and which versions will need to download it separately, please refer to this link. I wish to extend my thanks to Softpedia and Bleepingcomputer.com for these really useful links.

If for any reason, you wish to use the previous version of Edge (which uses the legacy rendering engine, please see this link for details of how to run the older version alongside its modern equivalent).

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
====================
In early January Mozilla released new versions of Firefox to address the following vulnerabilities and to add new user privacy features:

Firefox 72.0: Resolves 5x high severity CVEs (defined), 5x moderate CVEs and 1x low CVE

Firefox ESR 68.4 (Extended Support Release): Resolves 4x high severity CVEs and 2x moderate CVEs

More recently Firefox 72.0.1 was released to address a single critical severity zero day (defined) vulnerability which was responsibly disclosed to Mozilla and fixed very quickly. Finally Firefox 72.0.2  was released on the 20th of January resolving inconsistent playback of full-screen HD videos among non-security other issues.

Highlights from version 72 of Firefox include:
In addition to picture in picture enabled by default for macOS and Linux, it blocks the use of fingerprinting by default (the collection of data from your system e.g. browser version, font size, screen resolution and other unique data. This protection is provided by Disconnect. There are multiple levels of fingerprinting protection provided with the standard level being enabled by default. The strict level however may lead to websites not functioning as expected. Further details are available here.

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.

====================
Wireshark
====================
In mid-January the following Wireshark updates were released:

v3.2.1: Relating to 1 security advisory

v3.0.8: Relating to 1 security advisory

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 (v3.2.1 or v3.0.8). 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.

====================
Google Chrome

Google made available two security updates during November; the first resolves 3 vulnerabilities while the second resolves 16 vulnerabilities. The second also provides mitigation for the vulnerability disclosed by the NSA to Microsoft more commonly known as the  Chain of Fools/CurveBall or CVE-2020-0601 This test page from SANS will then show your system is no longer vulnerable after applying the second update. Please still apply the update from Microsoft to provide the most protection, Google’s changes are a mitigation only.

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.

Microsoft Ends Support for Windows 7, Server 2008 and Server 2008 R2

As you are likely aware, on Tuesday, 14th January Microsoft will end support for Windows 7, Windows Server 2008 and Windows Server 2008 R2.

Approximately, 27% of all Windows devices are using Windows 7 so many devices are potentially impacted.

For enterprise and organisations, please consider upgrading to a newer version of Windows. Further details of your options are available here (this link mentions newer versions of Windows Server after Windows Azure). For Windows 7 users, you can consider upgrading to Windows 10 or paying for extended security updates (for businesses and enterprises only). This article provides details of your options (my thanks to TechRadar for this article).

Application compatibility when migrating from Windows 7 to Windows 10 (or their Server equivalent) is very good. Microsoft (perhaps) conveniently states it at a 99% chance your applications will work without changes. For businesses they offer their Desktop App Assure service for assistance if a Windows 7 applications experiences issues on Windows 10.

====================
Update: 14th January 2020
====================
Further suggestions to better defend Windows 7, Windows Server 2008 and Windows Server 2008 R2 are the following (my thanks to itlab.com for this list):

  • Make the system offline only, if network access isn’t needed (take it off the wired or wireless network).
  • If network access is needed, put the system on a separate subnet and only permit access to and from it for authorized systems. Make sure to narrow the ports permitted to connect to and from this system so that only needed ports are open.
  • Remove all unnecessary apps and disable any unneeded services.
  • If the system is a virtual machine, take periodic snapshots of it, so if it becomes affected by a vulnerability, you can restore the snapshot easily.
  • Make certain this system is not permitted to access the internet unless it is necessary for functionality. Ensure a proxy server is in place and will only permit access to authorized sites.
  • Make sure the system has anti-malware software on it, and it’s regularly updated.

While Microsoft’s Extended Security Updates (ESU) paid for scheme applies to businesses of all sizes you may experience is fewer than 50 staff as evidenced by well known Microsoft blogger, Ed Bott in the his article. While further providers came forward after the article was published, please be aware that it may not be a simple process to be accepted for the scheme.

A practical list of Windows 7 FAQs is also available from here (my thanks to AskWoody.com for this)

Thank you.

Further updates were made available for the NVFlash tool (not applicable to end users) and Nvidia Geforce Experience. 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.

Exploits of BlueKeep Vulnerability Have Begun

In early November the security researcher Kevin Beaumont detected exploitation of the BlueKeep RDP vulnerability (patched in May 2019) within his honeypot network (defined).

How serious are these attacks?
At this time the attacks are not considered serious since the exploits are not using a wormable (automatic) means of spreading.

While this is true, Beaumont and Microsoft have cautioned that more stable exploits are likely to follow. Beaumont points to a blog post that discusses why the current exploits are mostly causing crashes upon systems and how to make the exploit more stable. Beaumont has stated over 724k system remain exposed to this vulnerability.

How can I protect my organisation or myself from this vulnerability?
For workstation systems, as recommended in my previous post, please install the Microsoft update if your system is vulnerable. Beaumont and Microsoft provide recommendations specific to organisations in their respective posts to both mitigate the vulnerability and to locate vulnerable systems within your network.

Thank you.

Apologies for the delay in updating this post due to professional commitments.

I wanted to provide details of this month’s security updates from Microsoft and Adobe. On the 8th of October, Microsoft made available their updates resolving 59 vulnerabilities more formally known CVEs (defined).

Separately Adobe made available their updates a week later:

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

Adobe Acrobat and Reader: 68x Priority 2 CVEs resolved (45x critical severity, 23x Important severity)

Adobe Download Manager: Priority 3 CVE resolved (1x Important severity)

Adobe Experience Manager: Priority 2 CVEs (1x Critical CVE, 7x Important and 4x Moderate severity)

Adobe Experience Manager Forms: 1x Priority 3 CVE (1x Important severity)

As always, if you use these Adobe products, please install the necessary updates as soon as possible prioritising the Adobe Acrobat/Reader and Experience Manager updates.

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

This month’s list of Known Issues from Microsoft is available within their monthly summary page and applies to all currently supported operating systems. All issues have workarounds at this time and none appear to be serious issues. The up to date list is available from their summary page.

As for stability, I have installed all of this month’s updates on my Windows 10 systems (Builds 18362.388 , 18362.418) most recently the new kb4522355 (for Windows 10 Version 1903 Build 18362.449) and have not experienced any issues. Indeed, this update was intended to resolve the issues e.g. among with the Start menu that caused me to advise not to install Windows 10 updates earlier this month. Obviously, please continue to backup and test your systems as you usually would before install widely rolling out these updates but in general you should be fine.

A further useful source of update related information is the Calendar of Updates.

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).

If you like and use it, please also consider supporting that entirely volunteer run website by donating.

====================
For this month’s Microsoft updates, I will prioritize the order of installation below:
====================
Microsoft Scripting Engine: CVE-2019-1307 CVE-2019-1308 CVE-2019-1366

VBScript Remote Code Execution Vulnerability: CVE-2019-1238 CVE-2019-1239

Azure Stack Remote Code Execution Vulnerability : CVE-2019-1372

Remote Desktop Client Remote Code Execution Vulnerability : CVE-2019-1333

MS XML Remote Code Execution Vulnerability: CVE-2019-1060

Windows Error Reporting Manager Elevation of Privilege Vulnerability : CVE-2019-1315

Please install the remaining 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
====================
On 22nd October Mozilla released Firefox 70 to address multiple critical vulnerabilities and to one again introduce further privacy features (see below):

Firefox 70: Resolves 1x critical CVE (defined)(but consisting of multiple vulnerabilities), 3x high CVEs, 8x moderate and 1x low CVE

Firefox ESR 68.2 (Extended Support Release): Resolves 1x critical CVE (but consisting of multiple vulnerabilities), 3x high CVEs, 5x moderate

Highlights from version 70 of Firefox include:

Details of improvements in the macOS and Windows versions of Firefox are provided in this article. The blocking of social networking tracking is discussed in another article.

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
====================
On October 22nd, Google released Chrome version 78.0.3904.70. This update resolves a high severity flaw that earned the researcher who reported it $20,000. The Multi-State Information Sharing and Analysis Center (MS-ISAC) stated “successful exploitation could allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions and perform unauthorized actions, or cause denial-of-service conditions.” In total, this update contains 37 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.

=======================
WinSCP:
=======================
In mid October; WinSCP version 5.15.5 was released upgrading it’s embedded version of Putty (the Windows SSH client) to 0.73 (along with its SSH private key tools to the same version) resolving 2 vulnerabilities (with one other issue possibly security related). WinSCP 5.15.6 has since been released as a non-security update.

Thank you.

Update: 8th October 2019

Unfortunately due to professional commitments I won’t be able to update this post today with details of Adobe’s and Microsoft’s updates. I will do so as soon as possible this week.

Thanks for your understanding.

Original Post
================
On the 23rd of September Microsoft issued two out of band (unscheduled) security updates to resolve 2 zero-day (defined) vulnerabilities. The vulnerabilities affect Internet Explorer and Windows Defender.

Microsoft has drawn criticism for adding confusion to these updates since they are not available on Windows Update but must be installed manually. For Windows 10 Version 1903 this prompted the release of kb4524147 which at this time I do NOT recommend you install since it is causing some systems not to boot, not being able to print and in some cases the Start menu is crashing.

With further security updates expected from Microsoft tomorrow, please await those updates and re-assess if you should install them. I’ll updater this post tomorrow with more information on the new monthly updates.

Separately since Windows Defender updates automatically you should have received the relevant anti-malware engine update (Version: 1.1.14700.5) 48 hours after the 23rd September.

Thank you.
