Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker places a malicious .dll file in a local directory on the machine or on a network share. An attacker would then have to wait for a user to run a program that can load a malicious .dll file, resulting in elevation of privilege. However, in all cases an attacker would have no way to force a user to visit such a network share or website.
