Package        : ikiwiki
Vulnerability  : missing input sanitising
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-2944

Josh Triplett discovered that the blacklist for potentially harmful TeX
code of the teximg module of the Ikiwiki wiki compiler was incomplete,
resulting in information disclosure.

The old stable distribution (etch) is not affected.

For the stable distribution (lenny), this problem has been fixed in
version 2.53.4.

For the unstable distribution (sid), this problem has been fixed in
version 3.1415926.

We recommend that you upgrade your ikiwiki 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

You may use an automated update by adding the resources from the
footer to the proper configuration.
