March 2019 Update Summary

====================
Updated: 21st March 2019
====================
Two of the vulnerabilities patched by Microsoft (CVE-2019-0797CVE-2019-0808) were zero day (defined) vulnerabilities being actively exploited in the wild. Four other vulnerabilities were publicly known (CVE-2019-0683CVE-2019-0754CVE-2019-0757 and CVE-2019-0809).

Separately the Google Chrome vulnerability mentioned below namely CVE-2019-5786 was also being exploited by attackers.

I have updated the suggested installation order (below) to reflect this new information. Thank you.

====================
Original Post:
====================
As scheduled; earlier today Microsoft and Adobe made available their security updates. Microsoft addressed 65 vulnerabilities (more formally known as CVEs (defined)) with Adobe resolving 2 vulnerabilities.

For Adobe; if you have not already done so; if you manage an installation of Adobe ColdFusion or know someone who does, please apply the necessary updates made available earlier this month. That update addressed a single priority 1 zero day (defined) vulnerability being exploited in the wild. Today’s Adobe updates are as follows:

Adobe Digital Editions: 1x priority 3 CVE resolved

January 2019 Update Summary

====================
Updated: 9th January 2019
====================
Happy New Year to all of my readers. Thanks very much.

Today Microsoft made available monthly updates resolving 47 vulnerabilities (more formally known as CVEs (defined)) respectively. Further details are available from Microsoft’s monthly summary page.

These mitigations (listed at the end of his in-depth discussion) will better defend your system(s) against a variant of this vulnerability which still remains relatively easy for an attacker to exploit.

Thank you.

November 2017 Security Updates

Back in November; Microsoft released their routine monthly security updates. These updates resolved 53 vulnerabilities with 14 individual updates (which are grouped when downloaded). As always these are detailed within Microsoft’s new Security Updates Guide.

Sorry for not posting this sooner; travelling for my job meant my time was much more limited.

Microsoft have listed 6 Known Issues that can occur from Windows 7 up to and including Windows 10 (version 1703):

Windows 10 (versions 1511, 1607 and 1703 potentially impacted):

KB4048954:

could cause Internet Explorer 11 to not provide users of SQL Server Reporting Services (SSRS) the ability to scroll through drop-down menus.

Windows Pro devices on the Current Branch for Business (CBB) will upgrade unexpectedly.

The above issue regarding Epson printers could also occur. All 3 of the above issues have been resolved. Please see KB4048954 for details of the additional updates containing the appropriate fixes.

KB4048953:

Details 2 of the above issues as well as an additional issue regarding an error message for the CDP User Service. Please see KB4048953 for details of the additional updates containing the appropriate fixes.

Windows 8.1 and Windows Server 2012 R2:

KB4048958

Please see KB4048958 for details of the additional updates containing the appropriate fixes for the issues already discussed above.

KB4048961

Please see KB4048961 for details of an additional update containing the appropriate fix for an issue already discussed above.

Windows 7 SP1 and Windows Server 2008 R2 Standard:

KB4048957

Please see KB4048957 for details of the additional updates containing the appropriate fixes for the issues already discussed above.

KB4048960

Please see KB4048960 for details of an additional update containing the appropriate fix for an issue already discussed above.

This month there are 4 Known Issues (kb4041691kb4042895 , 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.

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

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 Experience Manager (priority 3, 3 CVEs)

Adobe Flash Player (priority 2, 5 CVEs)

Adobe InDesign CC (priority 3, 1 CVE)

Adobe Photoshop CC (priority 3, 2 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.

In addition to installing the security update they recommend disabling the legacy equation editor to protect against future attackers against the code which does not benefit from the more secure coding practices.

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

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.

Thank you.

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

=======================
Apple security update:
=======================
An updates was made available by Apple on the 29th of November for macOS High Sierra to resolve a critical security vulnerability that could have resolved in the creation of a root (defined) account on the affected system allowing an unauthorised user privileged access to that system. Further details of this vulnerability are available here. As discussed in that link, this security update should have been installed automatically (no user action required).

=======================
Mozilla Firefox and Firefox ESR
=======================
During November Mozilla released security updates for Firefox and Firefox ESR(Extended Support Release) raising their version numbers to 57 (and later to 57.0.1) and 52.5 respectively.

  • Firefox 57 resolves 15 security issues more formally known as CVEs (defined) while 57.0.1 resolves 2 CVEs.
  • Firefox ESR 52.5 resolves 3 CVEs.

As always full details of the security issues resolved by these updates are available in the following links:

Firefox 57 and Firefox 57.0.1

Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, please update it as soon as possible to resolve these security issues.

August 2017 Security Updates Summary

It’s the second Tuesday of August and Microsoft and Adobe made available their monthly scheduled security updates.

Microsoft resolved 48 vulnerabilities in total more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

This month there is only 1 Known Issue for this month’s Microsoft updates.

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

Separately Adobe made available four security bulletins for the following products:

Adobe Digital Editions (priority 2, 2x critical, 7x important CVEs)

Adobe Experience Manager (priority 2, 1x important, 2x moderate CVEs)

Adobe Acrobat/Reader (priority 2, 43x critical, 24 important CVEs)

Adobe Flash (priority 1, 1x critical, 1x 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.

Of note this month is the particularly large Adobe Acrobat/Reader update and the very small Flash Player update. The number of vulnerabilities resolved in last month’s Flash Player update was also small but it is too early to tell if vulnerability is moving away from Flash Player due to Adobe’s recent notice of their intention to de-commission Flash Player in 2020.

=======================
Update:12th September 2017:
=======================
Adobe last month updated their Adobe Acrobat and Acrobat Reader again after the availability of the initial patches in order resolve a regression (defined). Please ensure your installations of these products are updated to the version detailed by Adobe in their updated security bulletin (or are more recent than those listed in the bulletin).

Thank you.

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 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.

—————
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 Windows Hyper-V

Windows Scripting Engine (affecting Edge, Internet Explorer and Office)

Microsoft Edge and Internet Explorer

Windows PDF Viewer

 

Important severity:

Windows Font Engine
====================

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.

Thank you.

June 2017 Security Updates Summary

Yesterday Microsoft and Adobe made available their monthly scheduled security updates.

Microsoft’s addressed a large number of vulnerabilities, 94 in total more formally known as CVEs (defined). These are detailed within Microsoft’s new Security Updates Guide.

At the time of writing there are three Known Issues for this month’s Microsoft updates (although all three knowledge base articles (4022717, 4022726, 4022715) describe the same iSCSI availability issue which is currently awaiting a resolution). The IT Pro Patch Tuesday blog hasn’t been updated since April and isn’t of assistance this time (and for that reason is becoming increasingly irrelevant).

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

This month again breaks the usual trend with these updates to offer a collection of updates for Windows XP and Windows Server 2003 which address the remaining vulnerabilities disclosed by the ShadowBrokers hacking team back in April this year. The majority of these updates were already released for more modern versions of Windows after the end of support dates for Windows XP (April 2014) and Windows Server 2003 (July 2015) respectively. Please review the detailed security advisory to download the appropriate updates for your systems. Further information is available in Microsoft’s blog posts here and here.

As with the update made available in May, these updates will not be available via Microsoft Updates or Automatic Updates. The availability of these updates provides mixed meanings; namely that while they were made available is positive. However for those corporations, organisations and individuals sing out dated versions of Windows, it provides them less reasons to migrate since it hints at an attitude that Microsoft will patch those system if the situation get very bad. While Microsoft worked to dispel this point, not everyone will be aware of their statement on this matter.

In a further break from the routine of Update Tuesday, I wanted to mention a further set of vulnerabilities found in Windows Defender which Microsoft patched last month. Please ensure your version of Windows is using the patched version of Windows Defender as detailed in this news article to address these issues.

====================
Separately Adobe made available four security bulletins to updates for the following products:

Adobe Captivate (1x priority 3 CVE)

Adobe Digital Editions (9x priority 3 CVEs)

Adobe Flash (9x priority 1 CVEs)

Adobe Shockwave Player (1x priority 2 CVE)

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.
