Matt Taggart uploaded new packages for wordpress which fixed the following security problem:
Critical core security bug in the HTML sanitation library more info: http://wp.me/pZhYe-qt
For the lenny-backports distribution the problems have been fixed in version 3.0.4+dfsg-1~bpo50+1.
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
