Debian Security Advisory DSA-1465-2                  security@debian.org

Package        : apt-listchanges
Vulnerability  : programming error
Problem type   : local
Debian-specific: yes
CVE Id(s)      : CVE-2008-0302

Felipe Sateler discovered that apt-listchanges, a package change history
notification tool, used unsafe paths when importing its python libraries.
This could allow the execution of arbitary shell commands if the root user
executed the command in a directory which other local users may write
to.

This security update fixes a regression in the previous one, which caused
the package to fail to work.

For the stable distribution (etch), this problem has been fixed in version
2.72.5etch1.

For the old stable distribution (sarge), this problem was not present.

For the unstable distribution (sid), this problem has been fixed in version
2.82.

We recommend that you upgrade your apt-listchanges package.


Upgrade instructions
- - --------------------

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

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

You may use an automated update by adding the resources from the
