Python buffer overflow A bug was found in the way python determines the realpath() of the current script. The realpath() function is broken by design and should not be used. http://www.gotfault.net/research/exploit/gexp-python.py http://www.gotfault.net/research/advisory/gadv-python.txt I can crash FC4 and RHEL4 with this exploit. Need to look at the source. It should have a low impact as you have to run a python program from within a direcotory which is part of an insanely long path. The other distributions are likely not crashing as the maximum path length returned by realpath() can differ. Further testing has shown that this issue ONLY affects a python program which resides inside the very long path (realpath, so you can't use symlinks to fake it, a hardlink will work though). Simply running a python program with your CWD very long does nothing. We don't allow suid python scripts, which means the only real path of exploitation would be to trick another user into doing something silly. consolehelper adds quite a lot of sanity to how we run python programs as root. This issue also affects FC4
