Microsoft Management Console File Format Denial of Service Vulnerability -
This vulnerability allows an unauthenticated attacker to create a denial of
service condition if the attacker can convince a user to open a share
containing a specially crafted .msc file. However, the attacker has no means
to force a user to visit the share or view the file.
The 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. Servers and
workstations are most at risk from this vulnerability. The update addresses
the vulnerability by correcting how Windows validates the destination buffers
in certain scenarios.
Microsoft received information about this vulnerability through coordinated
vulnerability disclosure. When this security bulletin was originally issued
Microsoft had not received any information to indicate that this vulnerability
had been publicly used to attack customers.
