This can be exploited to cause memory corruption and allows arbitrary code execution. 2) A boundary error exists within the Routing and Remote Access service (RRAS) service when handling certain RPC requests. This can be exploited to cause corruption of the RASMAN registry and allows arbitrary code execution. Successful exploitation on Windows XP SP2 and Windows Server 2003 requires valid logon credentials. On Windows 2000 SP4 and Windows XP SP1, the vulnerabilities can be exploited by anonymous users. SOLUTION: Apply patches.
