                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           MandrakeUpdate
Date:                   August 12th, 2000
Advisory ID:            MDKSA-2000:034

Affected versions:      6.0, 6.1, 7.0, 7.1
________________________________________________________________________

Problem Description:

 There is a possible race condition in MandrakeUpdate that has the
 potential for users to tamper with RPMs downloaded by MandrakeUpdate
 prior to them being installed.  This is due to files being stored in
 the /tmp directory.  This is a very low security-risk as most servers
 that provide user logins shouldn't be using MandrakeUpdate.  These
 updated versions provide a fix for the problem by using /root/tmp
 instead of /tmp.
________________________________________________________________________

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" or by using a version of RPM greater than 3.0 with
the command "rpm -K package_name".  This will also check the GnuPG 
signature of the package provided you have the public key as part of 
your keyring (the public key is provided at the end of this advisory).

________________________________________________________________________

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.
