I can't shed any more light on it, but I can look too :o) The original mailing of the patch to the list is below: http://www.uwsg.iu.edu/hypermail/linux/kernel/0607.1/1694.html [snip> The prctl() system call should never allow to set "dumpable" to the value 2. Especially not for non-privileged users. This can be split into three cases: 1) running as root -- then core dumps will already be done as root, and so prctl(PR_SET_DUMPABLE, 2) is not useful 2) running as non-root w/setuid-to-root -- this is the debatable case 3) running as non-root w/setuid-to-non-root -- then you definitely do NOT want "dumpable" to get set to 2 because you have the privilege escalation vulnerability <snip] Is it that something else is misbehaving and trying to dump core as root?
