Description:

Microsoft Windows and Windows Server could allow a remote attacker to execute arbitrary code, caused by a buffer overflow in the rendering of Windows Metafile (WMF) image formats.

An attacker could exploit this vulnerability by sending the malicious image to a victim as an email attachment and tricking the victim into opening the attachment or by hosting it on a Web site and persuading the victim to visit the Web site. A local attacker could exploit this vulnerability to obtain elevated privileges.
