Patch Analysis for February 2021

Welcome to this February Patch Monday Bulletin. This month there are patches from Adobe, Apple, Google, and Mozilla. Adobe Acrobat/Reader and Google Chrome both updated actively exploited vulnerabilities and should be top priority this month. CVE-2021-21017 is an arbitrary code execution vulnerability that has been observed exploiting Adobe Acrobat/Reader. This is the first Critical Priority 1 vulnerability in recent months and should be the top priority this month. CVE-2021-21148 is a heap buffer overflow in google chrome that has exploits reported in the wild. Adobe rated the Magento update as a Critical Priority 2 update and should be the next priority due to Magento being a popular target for attackers. Follow up with updates to Mozilla Firefox since it has been a popular target in the past. Review the environment for the presence of iCloud, Thunderbird, and the remaining Adobe products and assess whether patches should be applied.

Over the years we've had millions of visitors to UltimateWindowsSecurity.com. Every month we have thousands and thousands of visitors to our Security Log Encyclopedia which documents all of the Security Log event ID’s for Windows Server OS’s. Back in 2007 when SharePoint added auditing capability, I realized that my audience not only needed the event information from SharePoint but I also found a similar need in SQL Server and Exchange. So not only did I document the data but I also started to develop the means to extract that event data from these applications so that it’s accessible and useable to the end user. Some 8 years later and LOGbinder is continuing to grow as companies realize LOGbinder bridges the gap between these applications and their infosec team. Visit LOGbinder.com to download a free 30-day fully functional trial and see the security event data that you have literally been missing.

So, without further ado, here’s the chart of non-MS patches this month.
