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