Vulnerability Description	Bitmap (BMP) is an image file format used to store bitmap digital images. A remote code execution vulnerability has been discovered in the way GDI+ handles integer calculations for BMP files. 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.
