Welcome to this May Patch Tuesday Bulletin. This month was much less exciting than last with only 55 unique CVE’s, 8 technologies, 2 technologies with critical updates, and 2 vulnerabilities that have been publicly disclosed. CVE-2021-31204 and CVE-2021-31207 were both publicly disclosed vulnerabilities affecting Visual Studio and Microsoft Exchange, respectively. Both vulnerabilities were rated “less likely” to be exploited. Windows, SharePoint, and IE all had vulnerabilities with high CVSS scores and were rated as “Exploitation More Likely” so it will be important to ensure that these technologies are updated quickly. There were no known actively attacked vulnerabilities or vulnerabilities with exploits released.

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 MS patches this month.
