A vulnerability classified as critical has been found in Microsoft Windows up to XP (Operating System). Affected is an unknown code block of the component TrueType Font Handler. The manipulation as part of a CMAP Table leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT allow remote attackers to execute arbitrary code via a crafted CMAP table in a TrueType font (TTF) file, aka "TrueType Font CMAP Table Vulnerability."

The weakness was presented 10/08/2013 by ZombiE as MS13-081 as confirmed bulletin (Technet) via ZDI (Zero Day Initiative). The advisory is available at technet.microsoft.com. The public release was coordinated in cooperation with the vendor. This vulnerability is traded as CVE-2013-3894 since 06/03/2013. The exploitability is told to be difficult.
