Microsoft Patch Tuesday, November 2017

It's that time of the month again for Microsoft updates. November's Patch Tuesday brings with it patches for 53 CVEs as well as rollup security patches for Adobe Flash and Microsoft Office. 19 of those 53 are rated "Critical", 31 are rated "Important" and the final 3 are rated as "Moderate".

The vast majority of the "Critical" rated CVEs patch vulnerabilities in the Microsoft Scripting Engine again this month. The others patch vulnerabilities in Internet Explorer and Edge, so, as always, be careful of browsing to strange web sites or opening Office documents; Especially those links and documents that arrive in an unsolicted message or email.

Among the more severe vulnerabilities on the "Important" list include arbitrary code execution in Office components and several privilege escalation vulnerabilities that could potentially allow an attacker to execute malware at a SYSTEM or Administrative level.
