Welcome to this April Patch Monday Bulletin. This month we have updates from Adobe, Google, Mozilla, and Oracle. It was a big month for Google with a number of Chrome zero days (CVE-2021-21224, CVE-2021-21206, CVE-2021-21220). Luckily, Chrome will auto update to apply these patches, but the browser needs to restart. Consider forcing a restart for workstations that may leave Chrome open for days or weeks. Monitor the environment for related IDS events and strange application behavior that may be associated with Chrome. Mozilla released high severity updates for Firefox so make this the next priority. Adobe updated various products, but they were all Priority 3 which indicates they typically are not a target or do not have active exploits observed in the wild. Apply these updates at your discretion. March was a critical patch update month for Oracle so apply Java updates after testing. Finally, review the environment for Thunderbird installations and apply updates.

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.
