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

The vulnerability is caused due to an error in Windows Shell when
parsing shortcuts (.lnk) as certain parameters are not properly
validated when attempting to load the icon. This can be exploited to
automatically execute a program via a specially crafted shortcut.

Successful exploitation requires that a user is e.g. tricked into
inserting a removable media (when AutoPlay is enabled) or browse to
the root folder of the removable media (when AutoPlay is disabled)
using Windows Explorer or a similar file manager. Exploitation may
also be possible via network shares and WebDAV shares.

NOTE: This is currently being actively exploited in the wild via
infected USB drives.

SOLUTION:
The vendor recommends disabling the displaying of icons for shortcuts
(please see the Microsoft security advisory for details).

PROVIDED AND/OR DISCOVERED BY:
Reported as a 0-day.
