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.
