Mandrake A vulnerability exists with tcsh when using the in-here documents with the << syntax.

________________________________________________________________________

                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           tcsh
Date:                   November 13th, 2000
Advisory ID:            MDKSA-2000:069

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

Problem Description:

 A vulnerability exists with tcsh when using the in-here documents with
 the << syntax.  When doing this, tcsh uses a temporary file to  store 
 the data.  Unfortunately, the temporary file is not created  securely 
 and standard symlink attacks can be used to make tcsh overwrite 
 arbitrary files.
________________________________________________________________________

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 -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, so if you want an immediate upgrade, please use one of the two 
above-listed mirrors.
