Microsoft Windows GDI32.DLL WMF image rendering code execution

win-wmf-execute-code (23846) The risk level is classified as HighHigh Risk

Description:

Multiple applications that use the GDI32.DLL (Graphics Rendering Engine) to parse and display Windows Meta File (WMF) images could allow a remote attacker to execute arbitrary code on the system, caused by a vulnerability in the SETABORTPROC function. The Windows Picture and Fax viewer is the default application to handle files with the .wmf extension. By creating a malicious WMF image and hosting it on a Web site or sending it to a potential victim as an email attachment, a remote attacker could execute arbitrary code to gain complete control of a victim's system, if the attacker could persuade the victim to visit the malicious Web site or open the email attachment.

Note: It is reported that this vulnerability affects the Graphics Rendering Engine used by other vendors, including Mozilla Firefox and Wine.
