MS15-014: Vulnerability in Group Policy could allow security feature bypass: February 10, 2015

Summary

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass if an attacker, by way of a man-in-the-middle attack, causes the Group Policy Security Configuration Engine policy file on a targeted system to become corrupted or otherwise unreadable. This results in the Group Policy settings on the system to revert to their default, and potentially less secure, state.
