When mprotect()-ing the address range afterwards, no protection was checked regarding the protection of the file originally opened. So when you open /usr/bin/su RDONLY and SHARED you could afterwards change the mmapped region to READ\|WRITE. This gave the possibility to obtain root privs obviously.	1993-04-09 17:16:30 +00:00

when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.
