====================
On the 3rd of April, Microsoft released an out of band security update for the Microsoft Malware Protection Protection Engine. Further details are available in this separate blog post.

====================
Separately Microsoft have since issued an update, KB4099950 to resolve the issue detailed below affecting the network adapter on Windows 7.

The new update KB4099950 must be installed before KB4088875 and KB4088878 (I assume if this is not the case that KB4088875 and KB4088878 could be uninstalled first?)

If you were experiencing any of the following issues on Windows 7 or Windows Server 2008 R2, please install the above update to resolve them:

====================
A new Ethernet Network Interface Card (NIC) that has default settings may replace the previous NIC and cause network issues.

Static IP address setting are lost.

These symptoms may occur on both physical computers and virtual machine that are running VMware.
====================

Thank you.

====================
Update: 1st April 2018:
====================
Microsoft have issued an out of band update for Windows 7 SP1 64 bit and Windows Server 2008 R2 SP1 64 bit to resolve resolve a regression (an un-intentional coding error resulting in a previously working software feature no longer working, alternative definition here) which introduced an additional elevation of privilege (defined) security vulnerability in the kernel (defined) of these Windows version, please see my new post for further details.

This post has also been updated with further software releases (please see below).

If you have already checked for updates and are not seeing any being offered for your Windows 7 or Windows 8.1 system, please ensure your anti-malware software is up to date. This article explains why this change was implemented by Microsoft. It also provides recommendations of how to resolve the issue of no updates being available. Windows 10 is not affected by this issue.

A known issue of a second network adapter appearing within Windows 7 has also been documented. If this occurs for you with March’s updates, this news article may be of assistance in resolving it. It is anticipated that Microsoft will resolve this issue in this month’s upcoming security updates.

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

Microsoft states in each link above they are working on resolutions to these issues.

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

Adobe also made available their scheduled security updates for the following products:

Adobe Acrobat and Reader (priority 2, 56 CVEs)

Adobe Connect (priority 3, 5 CVEs)

Adobe DNG Converter (priority 3, 1 CVE)

Adobe Digital Editions (priority 3, 6 CVEs)

Adobe Shockwave Player (priority 2, 1 CVE)

As always the priority updates are Flash Player first and Adobe Acrobat (in that order).

One point to note is that Adobe Acrobat 11 (or XI) / Reader 11 are now out of support from November onwards. These will be the final updates they receive. Adobe recommends upgrading to Adobe Acrobat DC or Reader DC (as appropriate). Apart from the different user interface of the DC version, possible privacy concerns were raised about one of the components of this newer version namely RdrCEF.exe (the purpose of which is described here). The suggestions to resolve these concerns were:

  • Adding cloud.adobe.com to your Hosts file (defined) to redirect it to localhost (defined) (to prevent it disclosing any private info)
  • Blocking RdRCEF.exe from accessing the internet using your software firewall

A list of changes to the Windows Registry (defined) were suggested in this forum thread but it is not clear if these are effective.

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