Michael Meskes uploaded new packages for virtualbox-ose which fixed the following security problem:
Debian Bug #504149
Symlink vulnerability due to bad /tmp handling allowing an attacker to overwrite any files owned by the starting user of virtualbox.
For the etch-backports distribution the problem has been fixed in version 1.6.6-dfsg-3~bpo40+1.
For the lenny and sid distributions the problem has been fixed in version 1.6.6-dfsg-3.
If you don't use pinning (see ) you have to update the packages manually via "apt-get -t etch-backports install <packagelist>" with the packagelist of your installed packages affected by this update.  <http://backports.org/dokuwiki/doku.php?id=instructions>
We recommend to pin the backports repository to 200 so that new versions of installed backports will be installed automatically:
Package: * Pin: release a=etch-backports Pin-Priority: 200
