CVE-2009-1925

The TCP/IP implementation in Microsoft Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2 does not properly manage state information, which allows remote attackers to execute arbitrary code by sending packets to a listening service, and thereby triggering misinterpretation of an unspecified field as a function pointer, aka "TCP/IP Timestamps Code Execution Vulnerability."
