                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.
