CVE-2012-0031

First published: Thu Jan 12 2012(Updated: )

Apache 2.2 fixed a possible crash on shutdown if a child changes the sb_type field in the scoreboard. Since unprivileged children should not be able to affect the parent in this way, this is treated as a Low severity security issue [1]. The reporter has a nice writeup of the flaw as well [2].
