Microsoft Patch Tuesday January 2019 released its monthly set of security updates to address the vulnerabilities in its products today. There are 49 vulnerabilities with 7 rated critical for Remote Code Execution , 40 rated important and 2 rated moderate in severity. Moreover, these updates have addressed the issues in Adobe Flash Player, Internet Explorer, Microsoft Edge, Microsoft Windows, Microsoft Office, and Microsoft Office Services and Web Apps, ChakraCore, .NET Framework, ASP.NET, Microsoft Exchange Server and Microsoft Visual Studio. It is also worth noting that no zero-days were reported for the fresh start of 2019. But a deep look at the other critical updates would prove useful in keeping the gremlins on your machines at bay.

Microsoft advises that these updates be uninstalled to prevent crashes and other such difficulties. A patch management tool can patch these vulnerabilities. Details follow.
