                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           pam
Date:                   August 1st, 2000
Advisory ID:            MDKSA-2000:029

Affected versions:      6.0, 6.1, 7.0, 7.1
________________________________________________________________________

Problem Description:

 There is a problem with the pam_console module that incorrectly 
 identifies remote X logins for displays other than :0 (for example, :1,
 :2, etc.) as being local displays, thus giving control of the console
 to the remote user.  Because the remote user has control of the console
 they are able to issue commands to reboot the remote system after
 providing their password.  Please note that this vulnerability is only
 exploitable if the system is running a graphical login manager like
 gdm, kdm, or xdm and if XDMCP is enabled and remote access is granted.
 Users are highly recommended to upgrade to this version which fixes the
 exploit (thanks to Red Hat).
________________________________________________________________________

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.
