Hi Paul,
You asked me to actually describe the security I am concerned about, so I am going for it :
Imagine an ill-intentioned people, call it the attackers. By the mean of simply creating the following C application (based on classical "Hello word") :
#include needed header
int main (int argc, char * argv[]) { /* printf ( "Hello world!" ); */ GetOverlappedResult(0, NULL, NULL, FALSE);
return EXIT_SUCCESS;}
Running this application on wine, I get to have my crash, with the possibility of an exploit. So all I have to do know is to find a vector to make you and some other people willing to run my application.
I won't describe in detail the way to perform the exploit as : 1 - I don't know how to proceed and I don't want to 2 - It would be showing poor sense of responsibilities
If you can run an application ... it already can do everything!
No need to protect APIs against misuse, they run at the same privilege level as your code.
Ciao, Marcus
