Technical Information

Brief overview of the risk:
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 containing a specially crafted .msc file. However, an attacker would have no way of forcing a user to visit the share or view the file.

Detailed Information on the risk:

A denial of service vulnerability exists when Windows attempts to access a specially crafted .msc file to retrieve the icon information, and then fails to properly validate a destination buffer, resulting in a denial of service. An unauthenticated attacker could exploit this vulnerability by convincing a user to open a share containing a specially crafted .msc file.
