Package        : awstats
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
Debian Bug     : 365910

Hendrik Weimer discovered that awstats can execute arbitrary commands
under the user id the web-server runs when users are allowed to supply
arbitrary configuration files.  Even though, this bug was referenced
in DSA 1058 accidently, it was not fixed yet.

The new default behaviour is not ao accept arbitrary configuration
directories from the user.  This can be overwritten by the
AWSTATS_ENABLE_CONFIG_DIR environment variable when users are to be
trusted.

The old stable distribution (woody) does not seem to be affected by
this problem.

For the stable distribution (sarge) this problem has been fixed in
version 6.4-1sarge3.

For the unstable distribution (sid) this problem has been fixed in
version 6.5-2.

We recommend that you upgrade your awstats 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 at the end of this advisory:

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.
