Patch Analysis for May 2021

Welcome to this May Patch Monday Bulletin. This month there are updates from Adobe, Google, and Mozilla. The highest priority this month is updating Adobe Acrobat/Reader which is rated critical priority 1. Adobe stated that CVE-2021-28550 “has been exploited in the wild in limited attacks targeting Adobe Reader users on Windows”. This vulnerability is an Arbitrary Code Execution vulnerability that was anonymously reported to Adobe. Ensure that Chrome and Firefox are updated after you have reviewed updates for Adobe reader. Neither of these browsers had vulnerabilities that were particularly severe, but browsers are a top target for attackers. Updates for 8 other Adobe products were released this month, so it is important to perform a comprehensive review of Adobe products in the environment. Finally, review Thunderbird installations and deploy the updates at the admin’s discretion.

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.
