Protecting against the Windows Adobe Type Manager (ATM) Zero Day Vulnerabilities

=======================
Update: 15th April 2020
=======================
Microsoft have now issued updates for both of the Adobe Type Manager vulnerabilities. These updates apply to Windows 10, Windows 8.1 and Windows 7 (and their Windows Server equivalents):

https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-0938

https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1020

Please install these updates when you can. Thank you.

=====================
TL;DR
A patch for these vulnerabilities is expected at the next scheduled collection of updates to be released on the 14th of April. Until then be aware of attempts to have you open unexpected or suspicious files via clicking links on websites/within emails or opening email attachments. If you are using any version of Windows earlier than Server 2016, 2019 or Windows 10 (Version 1703 or earlier), evaluate if you wish to enable the workarounds until a patch is released. This vulnerability is of critical severity for Windows 8.1 and Windows 7, please be certain your staff are security aware not to open unknown or suspicious attachments/files.

A micro-patch is now available for Windows 7 and Windows 8.1 (including their Windows Server equivalents):

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

=====================
Update: 30th March 2020
=====================
0Patch have released a micro-patch for these vulnerabilities that is free of charge during these uncertain times (some micro-patches are usually paid for services from 0Patch).

The patch works by blocking Windows from using the common code path used by Windows Explorer, Font Viewer, and applications using Windows-integrated font support to display Adobe Type 1 PostScript fonts. The micro-patch does not protect against local attacks but does block the more important remote attack vector.

The micro-patch is available for Windows versions including Windows 7 and Windows Server 2008 R2 with ESU, Windows 8.1 and Windows Server 2012, both 32-bit and 64-bit:

Thank you.

=====================
Update: 28th March 2020
=====================
As detailed in Microsoft’s security advisory, these zero day (defined) vulnerabilities are of critical severity for Windows 8.1 and Windows 7. Please make certain your staff/users are security aware and strongly advise them not to open unknown or suspicious attachments/files. This is particularly severe when staff/users are likely working from home at this time and the security of systems they are using may not benefit from the firewalls/IPS and proxy servers of their primary work location. Staff/users may even be using their personal laptop/desktops to access corporate data during the current COVID-19 lockdown period.

If possible, please evaluate and implement the appropriate workarounds in Microsoft’s security advisory (which mitigate the vulnerabilities but have the least impact on your day to day work/activities) while the appropriate updates are not yet available.

Thank you.

=====================
Original Post:
=====================
I hope everyone is staying safe under the current circumstances.

Yesterday Microsoft published a security advisory describing the use of vulnerabilities within the Windows Adobe Type Manager (ATM) library by attackers to run unauthorised code on victim systems.

Why should these vulnerabilities be considered important?
If an attacker can persuade you to open a document (a document, you may have been expecting but the email it came in doesn’t look or sound quite right or by clicking a potentially useful link) they may be successful in remotely running code of their choice on your system.

According to Kaspersky a more likely scenario would be “attackers also can exploit this vulnerability through an extension to the HTTP called Web Distributed Authoring and Versioning (WebDAV), which allows users to collaborate on a document. Microsoft suggests disabling the WebClient service, which allows you to use this feature”

https://www.kaspersky.com/blog/windows-adobe-type-manager-vulnerability/34395/

For the attack to be successful you must be using a version of Windows older than Windows Server 2016 (Version 1703 or earlier), 2019 or Windows 10 (Version 1703 or earlier). If your version of Windows is newer as per Microsoft’s analysis : ”The possibility of remote code execution is negligible and elevation of privilege is not possible”.

How can I protect my organisation or myself from these vulnerabilities?
Until an update is made available, be aware and don’t open email attachments that look suspicious or click on links (from emails, while web browsing or via instant message clients) that you weren’t expecting or are suspicious.

If you are using an older version of Windows, consider implementing the workarounds provided by Microsoft in their advisory but please be aware of their potential impact to routine functionality before more widely enabling such workarounds:

Thank you and stay safe everyone both inside and outside of cyberspace.

Adobe Flash Player 2020 Update Tracker

As I have done in previous years this post will track the number of vulnerabilities patched within Adobe Flash for 2020. This will be the last year of tracking these numbers since Flash Player is due to be decommissioned at the end of 2020. The major browsers are taking slightly different approaches to the phase out but the result will be the same (FAQ: Flash Player Deprecation).

Mozilla plan to turn off Flash by default in Firefox 84 scheduled for release in December 2020. However it appears the option to re-enable it manually will still be present.

As you know, this post will be updated throughout the year with the details of vulnerabilities being patched and if they are being exploited in the wild.

Thank you.

=======================
14th January 2020: Adobe did not release any Adobe Flash updates this month.

11th February 2020: Adobe releases Flash Player v32.0.0.330 to resolve 1x critical priority 2 vulnerability.

10th March 2020: Adobe did not release any Adobe Flash updates this month.

14th April 2020: Adobe did not release any Adobe Flash updates this month.

12th May 2020: Similar to the previous 2 months, Adobe did not release any Adobe Flash updates in May.

9th June 2020: Adobe releases Flash Player v32.0.0.387 to resolve 1x critical priority 2 vulnerability.
=======================

Update: 19th February 2020: The timeline was created to include the Adobe Flash Player update for February 2020 and to record not updates were issued in January. At the time of writing no exploits for this critical vulnerability disclosed in February are known to be taking place.

Update: 21st April 2020: The timeline above was updated to document that no Flash Player updates were published in March or April 2020.

Update: 19th May 2020: The timeline above was updated to document that no Flash Player updates were published in May 2020. The main text of this post was updated to add Mozilla’s plans for Firefox’s removal of support for Flash later this year.

Update: 9th June 2020: The timeline above was updated to reflect the release of Flash Player v32.0.0.387. At this time no known exploits are in the wild for the vulnerability it resolves.

February 2020 Update Summary

Today marks the release of this year’s second wave of scheduled updates from Adobe and Microsoft. 42 vulnerabilities were resolved by Adobe with Microsoft addressing 99 CVEs (defined).

====================
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:
====================
Microsoft Scripting Engine: CVE-2020-0710 , CVE-2020-0711 , CVE-2020-0712 , CVE-2020-0713 , CVE-2020-0767

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

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.

Separately in late February Google released Chrome version 80.0.3987.122 to address 3 security vulnerabilities, the most severe being a zero day (defined) vulnerability designated CVE-2020-6418 which is a type confusion vulnerability within Chrome’s JavaScript (defined) and Web Assembly (defined) engine known as V8.

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.

====================
Nvidia
====================
On the 28th of February Nvidia released security updates for its drivers which power their Geforce, Tesla and Quadro/NVS GPUs as well and updates for its vGPU software (for Linux, Windows, Citrix Hypervisor, VMware vSphere, Red Hat Enterprise Linux KVM, Nutanix AHV). Not all updates for the vGPU software are available at this time but are in progress and will be released over the coming weeks (timelines are provided within Nvidia’s security advisory).

As was the case with November’s 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. The steps to install the drivers are located here. If you use the affected Nvidia graphics cards or software, please consider installing these updates.

====================
Intel Security Advisories
====================
Intel have released a series of security advisories this month. The advisories are prioritised below. If you use any of these products, software or devices, please update them as soon as possible especially in the case of the high severity advisories.

High
Intel CSME Advisory (Intel Management Engine (ME) Firmware)

Medium
Intel RWC3 Advisory
Intel RWC2 Advisory
Intel MPSS Advisory
Intel Renesas Electronics USB 3.0 Driver Advisory

Low
Intel SGX SDK Advisory

====================
VMware
====================
In the latter half of February, VMware released a critical security advisory to address vulnerabilities within the following product:

vRealize Operations for Horizon Adapter

If you use VMware vRealize Operations for Horizon Adapter, please install the applicable security updates (depending upon which version of this product you are using) as soon as possible.

====================
Wireshark
====================
In the final week of February, updates were released for Wireshark (I’ll detail only the 2 most recent versions here):

v3.2.2: Relating to 4 security advisories (relating to 4 CVEs)

v3.0.9: Relating to 3 security advisories (relating to 3 CVEs)

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 (v3.2.2 or v3.0.9). 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.

Thank you.

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:

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

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.

July 2019 Update Summary

As predicted; earlier today Adobe and Microsoft made available their usual monthly security updates addressing 5 and 77 vulnerabilities (respectively) more formally known as CVEs (defined):

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

Botnet Targeted Unpatched Counter-Strike Vulnerabilities

In mid-March the security firm Dr. Web published details of a botnet (defined) they were able to shut down affecting players of the classic first-person shooter (FPS) game; Counter-Strike 1.6.

Why should this development be considered significant?
The report made available by Dr. Web showed that at it’s height the botnet resulting from the distribution of the Trojan (defined) Belonard numbered up to 39% of all the available game servers (1951 out of 5000) listed for Counter-strike gamers to choose from.

How were gamers systems infected?
One of the popular services offering servers to play on exploited 2 zero day (defined) remote code execution vulnerabilities within the 1.6 version of the Counter-Strike client to install Trojan Belonard within a gamer’s system. Researchers from Dr. Web found that this game remains very popular and can be played by 20,000 individuals on average at a time.

Counter-Strike can make use of dedicated servers that gamers can choose to connect to. These servers offer reduced lag, greater reliability while some monetised servers offer access to special weapons and protection against bans.

In an example scenario, a gamer might launch the official Steam gaming client. The client automatically will display a list of servers the player can connect to. Those with the lowest (lower is better) ping rate will be displayed at the top of the list. This list will also contain publicly available Valve (the company which created and maintains the Steam client) servers. However, the Trojan Belonard once it has infected a system it re-orders the servers offered to another system (placing them high in the list you see) in order to spread further. You may think you are connecting to a server with a low ping when in fact connecting to a malicious server which then infects your system with the Trojan. It does this by exploiting a remote code execution (defined: the ability for an attacker to remotely carry out any action of their choice on your device) vulnerability within the Counter-Strike client. A more detailed description and diagram is available from Dr. Web’s analysis of this threat. Your system will now contribute to spreading the Trojan by re-ordering the server list we discussed above.

The botnet herder did this in order to make more money since their other more legitimate servers would also be displayed high in the list of servers and those charge a fee for their use.

What happened to this botnet?
Dr. Web was successful in disrupting this botnet by coordinating with the registrar of the reg.ru domain name to shut down the websites used by the Trojan thus protecting new gamers from becoming infected. Furthermore, the domain generation algorithm (DGA)(defined); is being monitored by Dr. Web in order to continue to sinkhole (defined) the domains the malware attempts to use to continue spreading itself.

How can I protect myself from this threat or clean it from my system if I am already infected?
Unfortunately; the only way to prevent this botnet from being re-activated by whoever created it is for the zero-day vulnerabilities within the Counter-Strike client to be patched. Given the age and lack of financial reward to Valve to do this; that is unlikely.

If you suspect or know your system is infected with this malware; update your anti-malware software and run a full system scan. If this does not remove the malware you can use the free version of Malwarebytes to perform a scan and remove the malware. If you suspect any remnants remain you can use the additional anti-malware scanners linked to on this blog to remove them. In this case; RogueKiller, AdwCleaner and PowerEraser would be the most suitable for this malware.

Thank you.

March 2019 Update Summary

====================
Updated: 21st March 2019

12th November 2019: Just like last month; Adobe has not released any Flash Player updates this month.

10th December 2019: Adobe has not released any Flash Player updates this month.

=======================
Update: 19th February 2019: The timeline was created to include the Adobe Flash Player updates for January and February 2019. At the time of writing no exploits for the issue fixed by the February update are known to be taking place.

Update 12th March 2019: The timeline was updated to reflect that Adobe did not issue Flash Player updates this month.

Update: 21st March 2019: The timeline was updated to reflect that Adobe did publish a Flash Player update for March 2019 but it is a non-security update.
