Debian Security Advisory                             security@debian.org

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

- ---------------------------------



  Potato was released for the alpha, arm, i386, m68k, powerpc and sparc

  architectures.
