Package: tcsh
Vulnerability: local exploit
Debian-specific: no

Proton reported on bugtraq that tcsh did not handle in-here documents
correctly. The version of tcsh that is distributed with Debian GNU/Linux
2.2r0 also suffered from this problem.

When using in-here documents using the << syntax 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.

This has been fixed in version 6.09.00-10 and we recommend that you
upgrade your tcsh package immediately.


wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.



Debian GNU/Linux 2.2 alias potato
