Re: [suse-security] fix for new elf loader bug?

An immediate hotfix that requires no patching or updates is to disable core
As mentioned in http://www.isec.pl/vulnerabilities/isec-0023-coredump.txt
(This is from the guy who discovered this problem - see
"A hotfix for this vulnerability is to disallow
processes to drop core. This can be accomplished by setting the hard
core size limit for users to 0 (e.g. ulimit -H -c 0, man limits.conf)."
But you can't do that in a running system. It won't affect running shells
of normal users. So you need to reboot, and then you would need to
reboot again to allow cores again. So it's easier to reboot only once
with a patched kernel...
