Description: eEye Digital Security has reported a vulnerability in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges.

This results in insecure permissions on a mapped memory segment thereby allowing manipulation of the contents. Successful exploitation allows execution of arbitrary code with escalated privileges. NOTE: This security issue does not affected Windows for x64 and Itanium-based systems. Solution: Apply patches.
