March 2018 Update Summary

====================
Update: 5th April 2018:
====================
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.

Thank you.

May 2017 Security Updates Summary

Today Microsoft and Adobe made available their expected monthly security updates.

Microsoft’s updates address 57 vulnerabilities more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

At the time of writing there are no Known Issues for this month’s Microsoft updates. The IT Pro Patch Tuesday blog while not updated since last month doesn’t contain this months updates yet.
====================

Before continuing with this months updates I wanted to provide information on a critical out of band (un-scheduled) update made available by Microsoft yesterday to address a vulnerability responsibly disclosed (defined) by Google Project Zero researchers Natalie Silvanovich and Tavis Ormandy within Microsoft’s Malware Protection Engine. The full list of affected products is listed within their security advisory. The exploit code for this vulnerability was later published within a tweet (which will not exploit the vulnerability).

I recommend updating your version of the Malware Protection Engine as soon as possible to version 1.1.13704.0 (or later) since this vulnerability when exploited by an attacker will lead to them obtaining system level access (NT AUTHORITY\SYSTEM)(defined)(namely the highest level of privilege within a Windows system) over an affected system.

====================
Also today Adobe issued two security bulletins for the following products:

Adobe Experience Manager Forms (1x priority 2 CVE)
Adobe Flash Player (7x priority 1 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 as appropriate and apply the recommended updates. Google Chrome users will have the updated version installed automatically later this week.

If you use any of the above-mentioned Adobe products, please review the security bulletins linked to above and apply the necessary updates. As always 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:
—————
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/

A further useful source of update related information is the Calendar of Updates. News/announcements of updates in the categories of General Software, Security 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.

—————
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 the Microsoft updates this month, I will prioritize the order of installation for you below:
====================
Critical severity:
Microsoft Malware Protection Engine
Microsoft Office
Microsoft Edge
Internet Explorer
Microsoft SMB (CVE-2017-0277, CVE-2017-0278, CVE-2017-0279)
====================

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 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.

Thank you.

=======================
As recommended on my Tools and Resources page, Hitman Pro (now part of Sophos Security) has been updated to version 3.7.20 (Build 286). This update resolves 3 important vulnerabilities relating to the driver the tool uses for scanning. Any previous version of the tool should update automatically when opened to the most recent version.

=======================
VideoLAN VLC:
=======================
=======================
Update: 25th May 2017:
=======================
Yesterday VideoLAN released version 2.2.6 of VLC for Windows only. It resolves the security issues listed below (assuming at least 2 heap overflows (given their use of the plural form)). This list came from the NEWS.txt file after installing version 2.2.6 since the detailed release notes on VideoLAN’s website have not yet been updated (and may not be until 2.2.6 is officially made available for macOS and Linux systems).

The update is currently being distributed via their automatic updater (upon opening VLC) and manually from their website (unexpectedly that page also contains tarballs for Linux):

Changes between 2.2.5.1 and 2.2.6:
———————————-

Video output:
* Fix systematic green line on nvidia
* Fix direct3d SPU texture offsets handling

Demuxer:
* Fix heap buffer overflows

———————————-

It was not known at the time version 2.2.5.1 was made available that the correction of “Fix potential out-of-band reads in subtitle decoders and demuxers” were actually security issues assigned to 4x CVEs discovered by CheckPoint security.

=================
Late last week VideoLAN released version 2.2.5.1 of VLC. This update is available for Linux, Apple Mac OS X and Windows. It addresses (at least) 13 security issues mentioned here (I’ll explain my numbering using the list below). This update is available for download for the above operating systems from this page.

If you use VLC, please update as soon as possible to address the above mentioned security vulnerabilities as well as the general software bugs that were resolved.

1. Security hardening for DLL hijacking environments
2. Fix potential out-of-band dereference in flac decoder
3. Fix potential out-of-band reads in mpeg packetizers
4. Fix incorrect memory free in ogg demuxer
5. Fix potential out-of-band reads in subtitle decoders and demuxers
6. Fix ADPCM heap corruption (FG-VD-16-067)
7. Fix DVD/LPCM heap corruption (FG-VD-16-090)
8. Fix possible ASF integer overflow
9. Fix MP4 heap buffer overflows
10. Fix Flac metadata integer overflow
11. Fix flac null-pointer dereference
12. Fix vorbis and opus comments integer overflows and leaks
13. The plugins loading will not load external DLLs by default. Plugins will need to LoadLibrary explicitly.

=======================
Notepad++:
=======================
On the 14th of May, Notepad++ made available a new version updating it to version 7.4. While it is not a security update it includes a security related improvement namely: Improve certificate verifying method.

This version has since been updated to version 7.4.1 to resolve a number of non-security issues. If you use Notepad++, please consider updating to the most recent version to benefit from the security improvement and the bug fixes it includes.

Please note, the 64 bit version of Notepad++ became available in September 2016. It allows the opening of larger files and includes High Entropy ASLR (Address Space Layout Randomization (defined)) on a 64 bit version of Windows. I have discussed HEASLR on this blog before and it’s an excellent security measure/control/mitigation (defined). Further information on HEASLR can be found on Alex Ionescu’s blog.

=======================
GIMP (photo editor):
=======================
The open source ((the source code (human readable code) is free to view and edit by the wider IT community) photo editor GIMP has made available version 2.8.22 which resolves one security vulnerability. If you use this editor, please update it to this version (or later).
