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.

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.

=======================
Update: 14th June 2017:
=======================
I wish to provide information on other notable updates from June 2017 which I would recommend you install if you use these software products. I only choose a small number of products to list here since it can easily become too many and I wish to highlight the security benefits of installing the latest version of applications many of us use everyday:

=======================
Mozilla Firefox:
=======================
Firefox 54.0

=======================
Mozilla Firefox ESR:
=======================
Firefox ESR 52.2

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.

=======================
Google Chrome:
=======================
Google Chrome: includes 30 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 update to take effect.
=======================

=======================
Wireshark 2.2.7 and 2.0.13
=======================
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 (v2.2.6) or v2.0.13). 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.
=======================

December 2016 Security Updates Summary

Today Microsoft and Adobe released their scheduled monthly security updates, the final scheduled set from both vendors for 2016.

Microsoft’s made 12 bulletins available. These updates address 47 vulnerabilities listed within Microsoft’s security bulletin summary (as before excluding the Adobe bulletin). These are more formally known as CVEs (defined).

As with previous months, fortunately this month (so far) there are no Known Issues detailed within the above mentioned summary page. Monitoring that page before deploying the updates as well as the IT Pro Patch Tuesday blog will keep you well informed enabling you to have the best opportunity to avoid potential issues. If any issues do arise, those pages should be your first places to check for solutions.

====================
Adobe made available 9 security bulletins which included their regular Flash Player update. 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 installed automatically alongside the updated version of Google Chrome which will most likely be made available by Google either later today or in the next 1 to 2 days.

The Flash Player update addresses 17x priority 1 CVEs. All of Adobe’s priority rating are explained in the previous link. The other 8 security bulletins can be summarised as follows:

Adobe Animate (APSB16-38): Addresses 1x priority 3 CVE.
Adobe Experience Manager Forms (APSB16-40): Addresses 2x priority 3 CVEs.
Adobe DNG Converter (APSB16-41): Addresses 1x priority 3 CVE.
Adobe Experience Manager (APSB16-42): Fixes 4x priority 2 CVEs.
Adobe InDesign (APSB16-43): Fixes 1x priority 3 CVE.
Adobe ColdFusion Builder (APSB16-44): Fixes 1x priority 2 CVE.
Adobe Digital Editions (APSB16-45): Fixes 2x priority 3 CVEs.
Adobe RoboHelp (APSB16-46): Fixes 1x priority 3 CVE.

If you use Flash or any of the above products, please review the security bulletins linked to above and apply the necessary updates.

You can monitor the availability of security updates for the majority of 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 making a donation.
—————

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.

As always; to assist with making the best use of your time when deploying these updates, I will prioritise the updates for you below:

This month is a little different than before since the Microsoft Internet Explorer and Microsoft Edge bulletins when combined address 6 vulnerabilities that are already publicly disclosed (defined). These should be followed by the Adobe Flash update which addresses a zero day vulnerability (defined). Next up would be Microsoft Office, the Windows Graphics component and the Microsoft Uniscribe update due to their criticality.

The remaining security updates can be installed when you have the time to do so. Detailed information on the contents of each security bulletin is published each month 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 5.5) 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 is in the process of being retired with the end of support scheduled for the 31st of July 2018.

As is my standard practice, I would recommend backing up the data on any device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.

March 2016 Security Updates Summary

Today is Microsoft’s Update Tuesday. Adobe have also released updates for Adobe Acrobat, Adobe Reader and Adobe Digital Editions (Adobe Flash was not updated today; more details on this below).

Similar to last month there are 13 Microsoft security bulletins resolving 44 security issues more formally known as CVEs (defined).

At the time of writing Microsoft’s Security Bulletin Summary does not list any Known issues for the security bulletins made available today. An alternative source for information on Known Issues is the IT Pro Patch Tuesday blog which is usually updated shortly after the release of the updates if any issues are encountered. No issues are listed at the time of writing.

Adobe’s updates for Adobe Acrobat DC, Acrobat XI, Acrobat Reader DC and Adobe Reader XI address 3 CVEs within these products. These vulnerabilities have been classified as critical but have been assigned Priority 2 by Adobe, meaning that these updates should be installed sometime within the next 30 days. Further details of these updates are available in this security bulletin. An update for Adobe Digital Editions was also made available resolving 1 critical CVE.

If you use any of Adobe’s PDF applications mentioned above or Adobe Digital Editions, please follow the above product links to the appropriate security bulletins and apply the necessary updates.

As mentioned in January; Adobe no longer supports Acrobat X and Adobe Reader X. They did not receive any updates within that bulletin and will no longer do so. Please upgrade to Adobe Acrobat DC/Acrobat Reader DC or Acrobat XI/Adobe Reader according to your preference.

=======================
Update: 10th March 2016:
Earlier today Adobe published an updated version of Flash Player bringing it to version 21.0.0.182. This update resolves 23 security issues (all have been assigned CVEs). Adobe AIR, their application runtime was also updated to version 21.0.0.176 within the same bulletin.

Please follow the above Adobe Flash Player bulletin link and apply the necessary updates as soon as possible due to the severity of the issues the Flash update addresses and since one issue, an integer overflow (defined) vulnerability CVE-2016-1010 is being exploited in targeted attacks.

Thank you.
=======================

Adobe within their PSIRT blog post mentioned that a security update for Flash Player will be available in the coming days. No reason(s) for the delay was/were given. Wolfgang Kandek of Qualys in a blog post makes educated guesses as to what may be the cause for the delay. I will update this post when the updates become available.

You can monitor the availability of security updates for the majority of 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.

To assist with the deployment of Microsoft’s security updates I would recommend prioritising them as follows: Internet Explorer, Microsoft Edge, Windows Graphics Fonts, Windows PDF Library and Windows Media (in this order) due to their critical severities and widespread use.

As always you can then install any remaining applicable updates beginning this round of updates with the Windows USB Mass Storage Class Driver Security update (more info here) due to it’s ease of exploitation and the level of access it can allow an attacker to obtain. Next I would recommend the Kernel Mode Drivers update and Microsoft Office update since exploitation of these vulnerabilities is listed as more likely in the Security Bulletin Summary.

One final 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 5.5) 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.

As always as a routine precaution I would recommend backing up the data on any device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.
