Microsoft Patch Tuesday Audit – November 2019

TL;DR - Go Straight to the November 2019 Patch Tuesday Audit Report.

Microsoft has resolved a total of 74 vulnerabilities in its November 2019 Patch Tuesday, including a Zero-Day Internet Explorer vulnerability (CVE-2019-1429) and an Excel vulnerability (CVE-2019-1457) that has been publicly disclosed.

Critical IE Zero-Day Vulnerability Patched

Following the critical Chrome Zero-Day Flaw earlier this month, Microsoft has resolved a Critical "Scripting Engine Memory Corruption Vulnerability" (CVE-2019-1429) in Internet Explorer that could allow for an attacker to execute code remotely.

Successful exploitation of this critical vulnerability could result in an attacker gaining the same privileges as the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

In addition to the IE Zero-Day vulnerability, Microsoft has resolved a publicly disclosed vulnerability (CVE-2019-1457) in Office Excel 2016 for Mac that could bypass security features. To successfully exploit the vulnerability, an attacker would have to embed a control in an Excel worksheet that specifies a macro should be run.

Microsoft also patched several vulnerabilities in the Windows Hyper-V, an add-on to the Windows Server OS that allows users to create and run virtual machines from within Windows.

Reminder for Windows 7 End of Life

Microsoft thought it would be a good time to remind all Windows 7 & Windows Server 2008/2008 R2 users that Microsoft will stop providing security updates after January 14th, 2020. This End of Life means no more bug-fixes, security patches or new functionality, making any user - personal or enterprise - significantly more susceptible to attacks. If your organization is still running on Windows 7, now's the time to prepare for its fast-approaching EOL date.
