Vulnerability Description A remote code execution vulnerability has been discovered in the way GDI+ handles integer calculations for Bitmap (BMP) files. BMP is an image file format used to store bitmap digital images. By persuading a user to open a specially crafted BMP image file, an attacker could take complete control of an affected system.

Update/Patch Available Apply patches: Microsoft Security Bulletin MS08-052
Vulnerability Details The vulnerability is due to a buffer overflow when GDI+ fails to properly processes a malformed header in a BMP image file. A remote attacker may trigger this issue by convincing a user to open a specially crafted BMP file. Successful exploitation of this vulnerability may allow execution of arbitrary code on an affected system.
