Patch Analysis for January 2021

Welcome to this January Patch Tuesday Bulletin. This month there are 83 unique CVE’s affecting 10 technologies, 4 technologies with critical vulnerabilities, 1 exploited technology, and 1 technology with publicly disclosed vulnerability details. CVE-2021-1647 was exploited in the wild and affects the Malware Protection Engine but updates are applied automatically. CVE-2021-1648 was publicly disclosed and is a privilege escalation vulnerability in Windows but Microsoft states that exploitation is less likely. Microsoft does rate CVE-2021-1709 and CVE-2021-1707 as more likely to be exploited so make sure that these vulnerabilities are remediated. CVE-2021-1709 is an elevation of privilege vulnerability affecting Windows and CVE-2021-1707 is a remote code execution vulnerability affecting SharePoint.

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.

"I liked your high level overview of patches in the table. There are so many sources of patch information which can be very specific or surrounded by other stuff that it’s refreshing to get everything summarised like this. The "Randy’s Recommendation" comment is useful starting point too. Please keep up the good work."
