Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name: apcupsd
Date: December 12th, 2000
Advisory ID: MDKSA-2000:077

Affected versions: 7.2
________________________________________________________________________

Problem Description:

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 command:
rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.

Linux-Mandrake 7.2:
13d0d7582dc9539fd43165caea173bc0 7.2/RPMS/apcupsd-3.8.0-1.1mdk.i586.rpm
4312c2eea1bc86e720c05be44555bd83 7.2/SRPMS/apcupsd-3.8.0-1.1mdk.src.rpm
________________________________________________________________________

To upgrade automatically, use =AB MandrakeUpdate =BB.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and uprade with "rpm -Fvh *.rpm".

You can download the updates directly from one of the mirror sites
listed at:

http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the "updates/[ver]/RPMS/" directory.
For example, if you are looking for an updated RPM package for
Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/". Updated source
RPMs are available as well, but you generally do not need to download
them.

Please be aware that sometimes it takes the mirrors a few hours to
update.
