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.
Please verify the update prior to upgrading to ensure the
integrity of the downloaded package. You can do this with the
rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
Updated packages are available in the "updates/[ver]/RPMS/"
directory. For example, if you are looking for an updated RPM
package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/".
Updated source RPMs are available as well, but you generally do not
need to download them.
