Debian Security Advisory DSA-1465-1 security@debian.org
http://www.debian.org/security/ Steve Kemp

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

Package : apt-listchanges
Vulnerability : programming erorr
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.

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
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.
