Microsoft has released fixes for 84 vulnerabilities, 10 of them critical, one publicly disclosed, and one zero-day that is already being exploited in the wild, in its first monthly security drop of 2021, with patches incoming for Windows OS, Edge (HTML-based), Office, Visual Studio, .Net Core, .Net Repository, ASP .Net, Azure, Malware Protection Engine, and SQL Server.
Although lighter than many of Microsoft’s 2020 releases, January’s Patch Tuesday update is still substantial in historical terms, and given the volume of ongoing cyber security incidents, there is every reason to expect that 2021 will bring similarly high volumes of fixes.
