Package : lintian
Vulnerability : insecure temporary directory
Problem-Type : local
Debian-specific: yes
CVE ID : CAN-2004-1000
Debian Bug : 286681

Jeroen van Wolffelaar discovered a problem in lintian, the Debian package checker. The program removes the working directory even if it wasn't created at program start, removing an unrelated file or directory a malicious user inserted via a symlink attack.

For the stable distribution (woody) this problem has been fixed in version 1.20.17.1.

For the unstable distribution (sid) this problem has been fixed in version 1.23.6.

We recommend that you upgrade your lintian package.

Upgrade Instructions
---------------------

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

If you are using the apt-get package manager, use the line for sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

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