The shared memory scoreboard in the HTTP daemon for Apache 1.3.x
before 1.3.27 allows any user running as the Apache UID to send a
SIGUSR1 signal to any process as root, resulting in a denial of
service (process kill) or possibly other behaviors that would not
normally be allowed, by modifying the parent.pid and
parent.last_rtime segments in the scoreboard.
