Microsoft Patch Tuesday - February 2018

Summary: Microsoft released its February 2018 monthly security advisories addressing 54 new vulnerabilities, with 14 rated critical, 38 rated important, and 2 rated moderate, affecting Outlook, Edge, Scripting Engine, App Container, and Windows. Among the critical issues, CVE-2018-0852 is a remote code execution vulnerability in Outlook that requires a user to open a specially crafted file, and CVE-2018-0850 is an Outlook elevation of privilege vulnerability triggered when a crafted email causes Outlook to load a local or remote message store over SMB.

What's compelling: Two of this month's 14 critical flaws sit in Outlook, the client your users open all day, and one of them fires on receipt of a crafted email rather than a click - so the patch window is the only control standing between an attacker and the mailbox.
