Vulnerability Description
A remote code execution vulnerability has been discovered in the Windows kernel. The Windows kernel is the core of the operating system. It provides system level services, allocates processor time to processes, and manages error handling. This vulnerability is caused by the improper validation of input passed from user mode through the kernel component of the graphics device interface (GDI). Successful exploitation of this vulnerability may allow execution of arbitrary code on an affected system.

Vulnerability Details
The vulnerability is due to an error in the Windows kernel that fails to properly validate input passed from user mode through the kernel component of GDI. A remote attacker may trigger this issue by convincing a user to open a specially crafted EMF image file. EMF is an image format that can contain both vector information and bitmap information. By persuading a user to open a specially crafted EMF image file, an attacker could take complete control of an affected system.

Protection Overview
By enabling this protection, SmartDefense will detect and block the transferring of malformed EMF files over HTTP. IPS-1 will detect and block attempts to transfer malformed EMF files over various network protocols.

In order for the protection to be activated, update your Security Gateway product to the latest SmartDefense update.
