awstats - missing input sanitising

Hendrik Weimer discovered that specially crafted web requests can
cause awstats, a powerful and featureful web server log analyzer, to
execute arbitrary commands.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in
version 6.4-1sarge2.

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

We recommend that you upgrade your awstats package.
