Debian Security Advisory DSA 810-1 – Several problems have been discovered in Mozilla, the browser of the Mozilla suite. Since the usual praxis of backporting apparently does not work for this package, this update is basically version 1.7.10 with the version number rolled back, and hence still named 1.7.8.
