Linux-Mandrake Security Update Advisory
Package name: apcupsd
Date: December 12th, 2000
Advisory ID: MDKSA-2000:077
Affected versions: 7.2
A problem exists with the apcupsd daemon. During startup,
apcupsd creates a PID file in /var/run with the ID of the daemon
process. This file is used by the shutdown script to kill the
daemon process. The /var/run/apcupsd.pid file is created with mode
666 permissions, meaning it is world-writeable. A malicious user
can overwrite the file with arbitrary process IDs and those
proceses will be killed instead of the apcupsd process during the
restart or stop of the apcupsd daemon.
