DESCRIPTION:
A vulnerability has been reported in Internet Explorer, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error in the Vector Markup
Language (VML) implementation (vgx.dll) when accessing objects that
are not correctly initialised or have been deleted. This can be
exploited to corrupt memory via e.g. a specially crafted web page.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
Apply patches.
