Subject: gdb and suid binaries - security?
Date: Wed, 03 Apr 2002 07:26:00 -0000 [thread overview]
Message-ID: <097201c1db23$feef79d0$b6010c0a@catdog> (raw)
Is it true that if gdb is debugging a suid binary then any calls they make
from the debugger are executed as that user? Couldn't one then execute
arbitrary instructions as root if you debugged something like su? Or even
worse, just call setuid(0) and let the program run to completion.
Oddly enough I've noticed that this actually fails on both FreeBSD and Linux
but it almost seems to be some mechanism outside of gdb. Does anyone know
how this works?
cheers,
Kris
