Amaya Rodrigo uploaded new packages for libapache2-mod-authnz-external which fixed the following security problems:
CVE-2011-2688 Remotely exploitable SQL injection in the mysql auth module.
For the lenny-backports distribution the problems have been fixed in version 3.2.4-2~bpo50+1.1.
For the stable distribution (squeeze) the problems have been fixed in version 3.2.4-2.1+squeeze1.
If you don't use pinning (see ) you have to update the package manually via "apt-get -t lenny-backports install <packagelist>" with the packagelist of your installed packages affected by this update.  <http://backports.debian.org/Instructions>
We recommend to pin (in /etc/apt/preferences) the backports repository to 200 so that new versions of installed backports will be installed automatically.
Package: * Pin: release a=lenny-backports Pin-Priority: 200
