Affected versions

Solution

You can resolve this problem by updating to the latest version of either stable or beta channels. If for some reason you are unable to update to a new version, patched versions to resolve the vulnerability are also available for releases 1.0 as well as 1.2 through 1.6.

Upgrading to the latest version

The easiest way to resolve the vulnerability is to update to the latest versions on whatever channel (stable or beta) are you currently using.

If you installed the .rpm package, you can update with:

sudo apt-get update
sudo apt-get upgrade
sudo /etc/init.d/apache2 restart
It is also possible to build from source.
