Description Vincent Danen 2012-01-12 18:49:39 UTC

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].
