Summary
The remote host is missing an update to mozilla-firefox announced via advisory DSA 837-1. Tom Ferris discovered a bug in the IDN hostname handling of Mozilla Firefox, which is also present in the other browsers from the same family that allows remote attackers to cause a denial of service and possibly execute arbitrary code via a hostname with dashes.
