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.

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.

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

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.

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 January’s Microsoft updates, I will prioritize the order of installation below. I will discuss this month’s out of band (outside of the regular schedule) patches for Meltdown and Spectre in a separate blog post; the relevant CVEs are still listed below. A useful list of all CVEs for this month is present here:

====================
CVE-2017-5753 – Bounds check bypass (known as Spectre Variant 1)

CVE-2017-5715 – Branch target injection (known as Spectre Variant 2)

CVE-2017-5754 – Rogue data cache load (known as Meltdown Variant 3)

CVE-2018-0802: Microsoft Office zero day (similar to Novembers Office equation editor vulnerability)

Microsoft Office (18 further CVEs)

Microsoft Edge and Internet Explorer (multiple versions of Edge and IE affected)

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

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.

For this month; please take extra care with your back up to ensure you can restore your systems should you wish to revert your systems prior to installing the Meltdown and Spectre patches should you wish to uninstall the Security only bundle of updates or the updates are causing your system to become unstable.

Thank you.

=======================
Wireshark 2.4.4 and 2.2.12
=======================
v2.4.4: 3 CVEs (defined) resolved

v2.2.12: 4 CVEs resolved

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 (v2.4.4) or v2.2.12). 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.

====================
Update: 24th January:
====================
Oracle:
====================
Oracle have resolved 237 vulnerabilities with the security updates they have made available this month. Further details and installation steps are available here. Within the 237 vulnerabilities addressed, 21 vulnerabilities were addressed in the Java runtime. 18 of these 21 are remotely exploitable without an attacker needing to obtain a user’s username and password (their credentials).

If you use any of the Oracle products listed here, please install the appropriate security updates as soon as possible.

Particular priority should be given to Oracle WebLogic Server and PeopleSoft due to documented incidents of attackers using such installations for crypto currency mining with one such incident resulting in more than USD $226,000 being mined. Further details are available in the following blog post from security vendor Onapsis.
=======================

=======================
Further updates released in January:
=======================
VMware Updates:
=======================
In early January; VMware issued security updates to address the Meltdown and Spectre vulnerabilities within some of their products. Another advisory  was also released later in January. The affected products/appliances are listed below. For virtual machines used with VMware Fusion and VMware Workstation, the steps listed within this knowledge base article should also be followed.

Please review the above linked to security advisories and knowledge base article and apply the necessary updates and mitigation steps.

Affected products/appliances:

  • VMware vCenter Server (VC)
  • VMware vSphere ESXi (ESXi)
  • VMware Workstation Pro / Player (Workstation)
  • VMware Fusion Pro / Fusion (Fusion)

=======================
Mozilla Firefox:
=======================
In January Mozilla issued security updates for Firefox and Firefox ESR (Extended Support Release):

Firefox 57.0.4 (2 mitigations added)

Firefox 58: 3x critical, 13x high, 13x moderate, 2x low CVEs

Firefox 58.0.1: 1x critical CVE

Firefox ESR 52.6: 1 high CVE

Firefox ESR 52.6: 2x critical, 8x high, 1x moderate

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.

=======================
Google Chrome:
=======================
In late January an update for Google Chrome was made available which included 53 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.

=======================
7-Zip
=======================
In late January a security researcher located 2 vulnerabilities within 7-Zip. He reported them to the developer Igor Pavlov who very quickly released an updated version; v18.00 Beta. This has since been updated to 18.01 Stable to fix further issues (NOT security related).

The alternative Windows file manager Directory Opus will include the updated 7-Zip DLL (defined) within their next release. Their current beta already contains these fixes.

While 7-Zip does not have many vulnerabilities discovered within it (which has both advantages and disadvantages), there appears to be an increasing emphasis on it since it is used by anti-malware software and other applications e.g. VMware Workstation. Thus when a security update is issued; all of this software should eventually include the fixes. This occurred last year with the release of 7-Zip 16.00 to resolve 2 other security vulnerabilities.

Separately, Malwarebytes updated their Anti-Malware product to version 3.4.4 to update the 7-Zip DLL (defined) within it. Further details are available in my March 2018 Update Summary blog post.

If you use 7-Zip, please ensure it is updated to resolve both this year’s vulnerabilities and last year’s vulnerabilities (if you hadn’t already installed version 16 or later). Please also update Malwarebytes Anti-Malware or Directory Opus if you use them.

=======================
Nvidia Geforce Drivers:
=======================
This driver update applies to Linux, FreeBSD, Solaris and Windows and mitigates the Meltdown security vulnerability (CVE-2017-5753). While Nvidia’s GPUs are not vulnerable to Meltdown or Spectre, the GPUs interaction with an affected CPU has the potential for exploitation.The steps to install the drivers are detailed here. I detailed where Nvidia list their security advisories in a previous blog post. More details about the Meltdown and Spectre vulnerabilities are available in this blog post.

=======================
Hitman Pro:
=======================
As recommended on my Tools and Resources page, Hitman Pro (now part of Sophos Security) has been updated to version 3.8.20 (Build 292). This update resolves 2 vulnerabilities relating to libraries (defined) the tool uses namely zlib and libpng. Any previous version of the tool should update automatically when opened to the most recent version.

October 2017 Security Updates Summary

As scheduled Microsoft released their monthly security updates earlier today. They address 62 vulnerabilities; more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

This month there are 4 Known Issues (kb4041691, kb4042895 , kb4041676 and kb4041681) for this month’s Microsoft updates. 2 of these issues relate to an exception error dialog box appearing, with the others causing a black screen, updates not to install in express , a BSOD and changing of display languages. Microsoft states in each link above they are working on resolutions to these issues.

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

Update: 18th October:

On the 16th of October Adobe released Flash Player v27.0.0.170 to address a critical zero day (defined) vulnerability being exploited in the wild (namely being exploited on computing devices used by the general public in their professional and personal lives)). The BlackOasis APT group are believed to operate in the Middle East. The group is using malicious Microsoft Office documents with embedded ActiveX controls which contain the necessary Flash exploit. This exploit later installs the FinSpy malware.

Please install this update as soon as possible for any device with Flash Player installed. Google Chrome has already automatically received the update while earlier today Windows 8.1 and Windows 10 began receiving it.

As always you can monitor the availability of security updates for most your software from the following websites (among others) or use Secunia PSI:

July 2017 Security Updates Summary

Earlier today as expected Microsoft and Adobe made available their monthly scheduled security updates.

Microsoft resolved a relatively large number of vulnerabilities at 54 in total more formally known as CVEs (defined). However it’s less than last month at 94. These are detailed within Microsoft’s new Security Updates Guide.

After 2 months of updates being released for versions of Windows which were no longer supported, this month is a return to the usual expected patches.

At the time of writing there are no Known Issues for this month’s Microsoft updates. The IT Pro Patch Tuesday blog which I routinely referenced is no longer available.

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

Adobe made available just two security bulletins for the following products:

Adobe Connect (priority 3, 2x important and 1x moderate CVE)

Adobe Flash (priority 1, 1x critical, 2x important CVEs)

The priority ratings are explained in this link. Depending on which version of Flash Player you have, please review the Adobe security bulletin or Microsoft bulletin (the link includes “April” in the URL but it is not a typo) as appropriate and apply the recommended updates. Google Chrome users should have the updated version installed automatically later this week (if not already available).

If you use any of the above-mentioned Adobe products, please review the security bulletins linked to above and apply the necessary updates. As per the established process the Flash update should be installed as soon as possible since exploit kits (defined) tend to take advantage of newly disclosed vulnerabilities very quickly.

 

You can monitor the availability of security updates for most your software from the following websites (among others) or use Secunia PSI:

If you use any of the above software, please install the appropriate updates as soon as possible. Steps for installing updates for Windows are provided on the “Protecting Your PC” page.

====================
For this month’s Microsoft updates, I will prioritize the order of installation for you below:
====================
Critical severity:

Windows Search

Microsoft Edge and Internet Explorer

NT LAN Manager Elevation of privilege (CVE-2017-8563)(Corporate users: please ensure to set a more secure LDAP setting as per this knowledge base article)

Windows Explorer (CVE-2017-8463)
====================

Please install the remaining updates at your earliest convenience.

As always you can find detailed information on the contents of each security bulletin within ComputerWorld’s Patch Tuesday Debugged column.

Another security pre-caution that you may wish to take if you have Microsoft EMET (please ensure your version of EMET is the most recent version 5.52) installed is to use it to protect you from Adobe Flash being used to exploit vulnerabilities when you open a Microsoft Office document or Adobe PDF file. I provide recommendations of how to do this at the end of the July 2015 Update Summary. Please note that Microsoft EMET will be out of support on the 31st of July 2018.

As noted in this new blog post, parts of EMET are to become available in the Creator’s Fall Update for Windows 10 set for release in September 2017.

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.

Note: This post marks the 300th post on this blog. Thank you very much to my readers and here’s to the next 300!

=======================
Update:8th August 2017:
=======================

=======================
Nvidia Geforce Drivers:
=======================
This update applies to Linux, FreeBSD, Solaris and Windows and resolves up to 9 security vulnerabilities. The steps to install the drivers are detailed here. I detailed where Nvidia list their security advisories in a previous blog post.

=======================
Putty:
=======================
Putty, the open source and highly popular SSH (defined) client for Windows, was updated to version 0.70 in early July. It contains 1 security fix and 2 non-security bug fixes  (see below).  It is downloadable from here.

=======================
Security fix: the Windows PuTTY binaries should no longer be vulnerable to hijacking by specially named DLLs in the same directory, even a name we missed when we thought we’d fixed this in 0.69. See vuln-indirect-dll-hijack-3.
=======================

If you use Putty, please update it to version 0.70. Thank you.
