Who is Vulnerable?
Vulnerability Description 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 code execution vulnerability has been discovered in the way that GDI+ allocates memory. The vulnerability is due to an error when GDI+ fails to properly calculate the necessary size of a heap buffer while processing malicious TIFF files. A remote attacker may trigger this issue by convincing a user to open a specially crafted TIFF image file. By persuading a user to open the malformed TIFF file, an attacker could take complete control of an affected system.
