Microsoft Patch Tuesday, October 2017

October is here and brings with it patches for 62 CVEs and a handful of additional advisories. 28 of the vulnerabilities patched are rated "Critical" and 34 are rated "Important". The largest number of vulnerabilities patched (18 total) reside in the Microsoft Scripting engine, which is primarily responsible for executing Javascript and VBscript embedded in websites. Also on the "Critical" list is a Remote Code Execution (RCE) vulnerability in the Windows SMB protocol. While there is no known exploit for the vulnerability right now, it was a similar vulnerability that WannaCry piggybacked on earlier this year. Other vulnerabilities on the "Critical" list affect the Microsoft DNSAPI, so be aware of this if you run Microsoft's DNS service, as well as RCE vulnerabilities in the Graphics Engine.

On the list of vulnerabilities rated as "Important", common software like Internet Explorer, Edge, Skype for Business and Microsoft Office are patched. Patches for general Windows components are also listed including some Privilege Escalation vulnerabilities that malware often uses to execute at a higher privilege like Administrator or System.
