February 2017 Security Updates Summary

As I am sure you are aware the release of Microsoft’s security updates were delayed as per their blog post. I will detail Adobe’s scheduled updates below and update this post when they are available.

====================
Adobe made 3 security bulletins available for Adobe Flash , Adobe Digital Editions and Adobe Campaign. The Flash Player bulletin resolves 13x priority 1 vulnerabilities. The Digital Editions and Campaign updates addressing 9 and 2 vulnerabilities respectively (both sets are priority 3). Adobe’s priority rating are explained in this link.

Depending on which version of Flash Player you have, please review the Adobe security bulletin or Microsoft bulletin (link to be added when available) 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.

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

While there may only be 3 Microsoft bulletins this month, I will prioritise the order of updates for you below:

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 5.51) 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 always, 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.

US CERT Warns of Possible SMB Zero Day Vulnerability

Earlier this month saw the end of operations for a group known as the Shadow Brokers (who were responsible for the disclosure of critical security vulnerabilities in enterprise networking infrastructure). Their online auction of exploits remains open.

Among the exploits for sale is a possible zero day (defined) SMB (defined) exploit for Windows. With the potential use of this exploited predicted, the US-CERT issued a security advisory, which suggested disabling SMB version 1 and disabling the use of SMB version 2 at the network perimeter (preventing external access or internal traffic reaching outside of the corporate network). As previously noted on this blog, securing the use of SMB version 2 in this manner will also protect against the Redirect to SMB vulnerability.

These recommendations should better secure your corporate network against this exploit as well as future vulnerabilities.

Thank you.

January 2017 Security Updates Summary

Earlier today Microsoft and Adobe released their scheduled monthly security updates.

Microsoft only made 4 bulletins available. These updates address 3 vulnerabilities listed within Microsoft’s security bulletin summary (as before excluding the Adobe bulletin). These are more formally known as CVEs (defined).

Once again; there are no Known Issues listed within the above summary page. At the time of writing the IT Pro Patch Tuesday blog does not list any Known Issues. However, please check it before deploying your security updates just to be sure. As always, if any issues do arise, those pages should be your first places to check for solutions.

Next month Microsoft will only be publishing it’s security bulletins and release notes within their Security Updates Guide; rather than distributing this information across several pages. This post from WinSuperSite explains the changes in full.

====================
Adobe made a pair of security bulletins available for Adobe Flash and Adobe Acrobat/Adobe Reader. The Flash Player bulletin resolves 13x priority 1 vulnerabilities. The Adobe Acrobat/Adobe Reader resolves 29x priority 2 vulnerabilities. Adobe’s priority rating are explained in the previous 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 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.

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

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.

While there may only be 3 Microsoft bulletins this month, I will prioritise the order of updates for you below:

The update for Microsoft Office should be installed first due to it’s criticality. This should be followed by the update for Microsoft Edge and finally by the LSASS update. The update for Edge is important due to exploit kits relying on such patches not to be installed in order to spread further malware (defined).

As always you can find 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 5.51) 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 to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.

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.

October 2016 Security Updates Summary

====================
Update: 2nd November:
Last week Adobe made available an out of band (unscheduled) security update to Adobe Flash. This was due to a zero day (defined) vulnerability being exploited in limited targeted attacks (using spear phishing (defined) emails sometimes originating from previous victims of this vulnerability).

To protect your organisation or yourself from this vulnerability please install the Adobe Flash update if you make use of Flash Player on your organisations devices or your own individual systems. This link can be used to test if Flash Player is already installed.

This vulnerability is related to an APT (defined) group’s activity that is detailed in a more recent post.

Thank you.

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

This month saw an unusually high number of 5 Microsoft zero day (defined) vulnerabilities being addressed. For this reason, please prioritise the deployment of the following updates: Microsoft Graphics Component, Microsoft Internet Explorer, Microsoft Edge, Microsoft Internet Messaging API and Microsoft Office.

Once these updates are deployed, please move onto Adobe’s Flash Player update (to version 23.0.0.185) addressing 12 critical vulnerabilities, should be installed next if you already have a previous version installed. Due to the high number of vulnerabilities patched this month in Adobe Acrobat/Adobe Reader this should be installed next if you use their PDF creation/reader software.

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.
