DESCRIPTION:
iDEFENSE Labs has reported a vulnerability in Microsoft Windows,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error in the
Step-by-Step Interactive Training component when handling bookmark
link files. This can be exploited to cause a stack-based buffer
overflow via a specially crafted bookmark link file containing an
overly long string in the "User" field.

Successful exploitation requires that the user e.g. visits a
malicious web site or opens a malicious attachment.

SOLUTION:
Apply patches.
