Ways of Preventing Injected DLL Crashes

[Jason]

Windows has some available pointer functions you can use:

IsBadWritePtr IsBadWritePtr function
IsBadReadPtr IsBadReadPtr function

which you can condense with your own macro:

#define IsBadPtr(ptr,sz) (IsBadReadPtr((LPVOID)(ptr),(sz)) || IsBadWritePtr((LPVOID)(ptr),(sz)))
