Summary

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a remote, unauthenticated attacker convinces a user to open a share that contains a specially crafted .msc file. However, an attacker would have no way of forcing a user to visit the share or view the file.
