Vulnerability name/brief description MS12-033 - Vulnerability in Windows Partition Manager Could Allow Elevation of Privilege (2690533)
CVE/CAN name
Vendor threat level Important
SophosLabs threat level Medium
Solution MS12-033
Vendor description This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The security update addresses the vulnerability by correcting the way that Windows Partition Manager allocates objects in memory.
SophosLabs comments This privately disclosed vulnerability happens when two or more processes or threads call the Plug and Play (PnP) Configuration Manager functions at the same time. In order to take advantage of this vulnerability, the attacker would require access to the targeted system so as to execute arbitrary exploit code in kernel mode in order to gain control of the system. As this vulnerability was privately disclosed and also requires access to the targeted system, its impact is largely mitigated.
