win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 on 64-bit platforms does not properly validate pointers during the parsing of OpenType (aka OTF) fonts, which allows remote attackers to execute arbitrary code via a crafted font file, aka "Win32k OTF Validation Vulnerability."

The remote host is running a version of the Windows kernel that is affected by a remote code execution vulnerability.  An attacker can exploit this by causing a user to visit a network share containing a specially crafted OpenType font (OTF).  The attacker can exploit this issue to execute arbitrary code in kernel mode and take complete control of the affected system.
