| 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 EMF files over HTTP. No update is required to address this vulnerability.
Since the protection offered in this advisory may degrade performance and block access to legitimate files, users are advised to use this protection as a workaround till all systems are patched.
Users are protected against this vulnerability if the WMF/EMF protection for blocking vulnerable files in the Protection section of CPAI-2006-020 has been applied.
