Detailsinfo

A vulnerability, which was classified as problematic, has been found in Microsoft Windows Server 2008/Vista (Operating System). This issue affects the function NtUserCheckAccessForIntegrityLevel. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Use-after-free vulnerability in the kernel-mode drivers in Microsoft Windows Vista SP1 and SP2 and Server 2008 Gold and SP2 allows local users to gain privileges or cause a denial of service (system crash) by using a large number of calls to the NtUserCheckAccessForIntegrityLevel function to trigger a failure in the LockProcessByClientId function, leading to deletion of an in-use process object, aka "Win32k Reference Count Vulnerability."

The weakness was released 07/05/2010 with Microsoft-Spurned Researcher Collective (MSRC) as EDB-ID 14156 / MS10-073 / MS10-098 as confirmed exploit (Exploit-DB).
