Description:
Multiple vulnerabilities were reported in the Windows operating system. A remote user can cause arbitrary code to be executed on the target user's system. A local user can obtain elevated privileges on the target system.
A remote user can create a specially crafted TrueType font that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2011-3402, CVE-2012-0159]. The code will run with the privileges of the target user.
A local user can trigger a windows and messages handling flaw in the Windows kernel-mode driver (win32k.sys) to execute arbitrary code in the context of another process [CVE-2012-0180].
A local user can trigger a keyboard layout file processing error in the Windows kernel-mode driver (win32k.sys) to execute arbitrary code in the context of another process [CVE-2012-0181].
A local user can trigger a scrollbar calculation flaw in the Windows kernel-mode driver (win32k.sys) to execute arbitrary code in the context of another process [CVE-2012-1848].
Alin Rad Pop (via Tipping Point's Zero Day Initiative), Tarjei Mandt of Azimuth Security, Nicolas Economou of Core Security Technologies, Geoff McDonald of Symantec, and h4ckmp reported these vulnerabilities.
