                Linux-Mandrake Security Update Advisory


Package name:           mgetty
Date:                   August 31st, 2000
Advisory ID:            MDKSA-2000:042

Affected versions:      6.0, 6.1, 7.0, 7.1

Problem Description:

There is a problem in the mgetty package, which contains a number of tools for sending and receiving faxes. The faxrunq tool uses a marker file in the /tmp directory, which is world-writable, in an insecure fashion. This problem, if exploited, allows malicious users to overwrite files on the system via a symlink attack which are owned by the user that is invoking faxrunq. All versions of mgetty prior to 1.1.22 are vulnerable.


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 « MandrakeUpdate ».

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

You can download the updates directly from:
ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates
ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors 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 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.

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.
