Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name: joe
Date: November 20th, 2000
Advisory ID: MDKSA-2000:072

Affected versions: 6.0, 6.1, 7.0, 7.1, 7.2
________________________________________________________________________

Problem Description:

When exiting joe in a non-standard way (such as a system crash, closing
an xterm, or a network connection going down), joe will unconditionally
append its open buffers to the file DEADJOE. This can be exploited by
the creation of DEADJOE symlinks in directories where root would
normally use joe. In this way, joe could be used to append garbage to
potentially sensitive files, resulting in a denial of service or other
problems.

Users of Linux-Mandrake 7.0 and earlier should also note that joe's
configuration files have moved from /usr/lib/joe to /etc/joe.
________________________________________________________________________

Please verify these md5 checksums of the updates prior to upgrading to
ensure the integrity of the downloaded package. You can do this by
running the md5sum program on the downloaded package by using
"md5sum package.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, so if you want an immediate upgrade, please use one of the two
above-listed mirrors.
