October 2018 Microsoft Patch Tuesday

Microsoft released patches for 48 vulnerabilities today and one advisory regarding a defense in depth update for Office. No Adobe updates are included so far, but Adobe has released updates to PDF Reader / Acrobat about a week ago.

Two vulnerabilities have been disclosed before:

CVE-2018-8531: A memory corruption vulnerability in the Azure IoT Device Client SDK (rated important)

CVE-2018-8432: A remote code execution vulnerability in the JET database engine (this issue was widely covered. It requires an attacker to convince the victim to open a malicious JET database file. Office products include JET).

CVE-2018-8453: This vulnerability, a privilege escalation issue in Win32k, was already exploited in the wild.

CVE-2018-8497: Another privilege escalation issues that was made public prior to today but not yet seen in exploits per Microsoft.
