Microsoft Windows Enhanced Metafile (EMF) buffer overflow
| win-emf-bo (16581) |  High Risk |
Description:
Microsoft Windows is vulnerable to a buffer overflow, caused by improper bounds checking when handling Enhanced Metafile (EMF) image formats. By creating a specially-crafted EMF image file containing malicious script, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the victim, once the file is opened. An attacker could exploit this vulnerability by hosting the malicious file on a Web site or by sending it to a victim as an HTML email.
Note: This vulnerability is different than the vulnerability addressed in Microsoft Bulletin MS04-011.
