An old ld-linux.so hole
...spawn.c should open a file (called .lock ) receiving descriptor lock_fd and set
a close-on-exec flag on it. Then spawn.c executes flock(lock_fd,LOCK_EX).
Another program ( called noloop ) opens .lock and performs
flock(noloop_fd,LOCK_EX) as well ( and goes to sleep). We also spawn a program
called eat_time, which simply does for(;;);, generating some load on the
machine.
A great moment occures: spawn.c does execl("/usr/bin/passwd",long_arg0,0).
As some load on the machine is imposed by eat_time, system call exec ( which
is time-consuming) should use whole time quantum available for spawn....
