The DLLs for XP SP2 and 2003 SP1 were compiled with Visual Studio's stack protection flag (/GS). This prevents a standard return address overwrite from working. The wcscpy() method everyone is using in their exploits is also blocked by another change in how the compiler orders and passes arguments. The standard way to bypass /GS is to use a SEH ptr overwrite, but so far, it doesn't seem possible to reach a SEH ptr with the overflow, when using the PathCanonicalize method.

Is there any technical reason that an exploit cannot be developed against XP SP2 and Server 2003 SP1? Or is this only a limitation of the current Metasploit exploit?
