Detailed Description

Business Impact: Although this vulnerability is in a core component of Microsoft Windows operating systems, it only affects Windows Vista and 2008.  Exploitation is remote (although  the attacker has to be on the victim's local network) and does not require any user interaction.  Successful exploitation provides the attacker with complete control of the end user's system.

Technical Description:

Microsoft Windows could allow a remote attacker to execute arbitrary code on the system, caused by the improper validation of MIME headers by the Web Service on Devices API (WSDAPI). By sending a specially-crafted WSDAPI message containing a MIME header or a query response to the WSD services running on TCP port 5357 and 5358, a remote attacker could exploit this vulnerability to execute arbitrary code on the system.

Remediation:

Patches are available. See References for details.
