Name of the Vulnerable Software and Affected Versions Microsoft Windows Server 2003 SP2 Microsoft Windows Vista SP2 Microsoft Windows Server 2008 SP2 and R2 SP1 Microsoft Windows 7 SP1 Microsoft Windows 8 Microsoft Windows 8.1 Microsoft Windows Server 2012 Gold and R2 Microsoft Windows RT Gold and 8.1

Description The Windows kernel-mode driver does not properly initialize function buffers, allowing local users to obtain sensitive information from kernel memory. This could possibly bypass the Address Space Layout Randomization (ASLR) protection mechanism via a crafted application. An attacker could use this information disclosure to gain information about the system, which could then be combined with other attacks to compromise the system. The information disclosure by itself does not allow arbitrary code execution, but it could be used in conjunction with another vulnerability to bypass security features.

Recommendations For Microsoft Windows Server 2003 SP2, update to a newer version to mitigate the risk. For Microsoft Windows Vista SP2, update to a newer version to mitigate the risk. For Microsoft Windows Server 2008 SP2 and R2 SP1, update to a newer version to mitigate the risk. For Microsoft Windows 7 SP1, update to a newer version to mitigate the risk. For Microsoft Windows 8, update to a newer version to mitigate the risk. For Microsoft Windows 8.1, update to a newer version to mitigate the risk. For Microsoft Windows Server 2012 Gold and R2, update to a newer version to mitigate the risk. For Microsoft Windows RT Gold and 8.1, update to a newer version to mitigate the risk. As a temporary workaround, consider restricting access to the kernel-mode driver to minimize the risk of exploitation.
