DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Visio, which can
be exploited by malicious people to compromise a user's system.

1) An error in ormelems.dll when parsing the VisioDocument stream can
be exploited to dereference an object that has not been completely
initialised via a specially crafted Visio file.

2) An error in elements.dll when parsing certain structures can be
exploited to corrupt memory via a specially crafted Visio file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

SOLUTION:
Apply patches.
