Symptoms

After applying MS15-A02 KB3033929, the superseded patch MS12-001 KB2644615 is showing as missing

Cause

The introduction of MS15-A02 in March 2015 opened up a security hole that is addressed by the installation of MS12-001 KB2644615 or MS13-063  KB2859537. Although MS13-077 supersedes both of those patches, it does not take care of the vulnerability opened up by MS15-A02.

Resolution

Deploy MS12-001 KB2644615 based on the scan results from Shavlik Protect or download the install file for MS13-063 KB2859537 and manually run the file on the target machine
