Mandrake cons.saver does not check if it is started with a valid stdout, which combined with a bug in its check to see if its argument is a tty

________________________________________________________________________

                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           mc
Date:                   December 12th, 2000
Advisory ID:            MDKSA-2000:078

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

Problem Description:

 A problem was found in the cons.saver program by Maurycy Prodeus.  The
 cons.saver program is a screensaver for the console that is included in
 the mc package.  cons.saver does not check if it is started with a
 valid stdout, which combined with a bug in its check to see if its
 argument is a tty (it forgets to close the file-descriptor after
 opening the supposed tty), causes it to write a NULL character to the
 file given as its parameter.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
   http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.

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 -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.
