Vulnerability Description A remote code execution vulnerability has been discovered in the way that GDI+ allocates buffer size when handling WMF image files. The Microsoft Windows graphics device interface (GDI) enables applications to use graphics and formatted text on the video display and on the printer. A remote attacker may trigger this issue via a specially crafted WMF image file. Windows Metafile (WMF) is a 16-bit metafile image format optimized for the Windows operating system that can contain both vector information and bitmap information. Successful exploitation would allow execution of arbitrary code on a vulnerable system.

Update/Patch Available Apply patches: Microsoft Security Bulletin MS09-062
Vulnerability Details The vulnerability is due to an integer overflow when GDI+ fails to properly process malformed WMF image files. A remote attacker may trigger this issue by convincing a user to open a specially crafted WMF image file. By persuading a user to open the malformed WMF file, an attacker could take complete control of an affected system.

Protection Overview
