                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 -Uvh package_name".

You can download the updates directly from:

Or try one of the other mirrors listed at:


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.
