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
http://secunia.com/advisories/15341 )

"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)."
