eEye Digital Security has reported a vulnerability in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a race condition in the kernel's Virtual DOS Machine (VDM) implementation. 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.
