Description Jan Lieskovsky 2010-06-23 17:54:27 UTC 
Ludwig Nussel reported:
  [1] http://www.openwall.com/lists/oss-security/2010/06/23/4

a deficiency in the way avahi daemon processed packets with corrupted 
checksum(s). A remote attacker on the same local are network (LAN)
could send a DNS packet with broken checksum, that would cause avahi-daemon
to exit unexpectedly due to a failed assertion check. Different vulnerability
than CVE-2008-5081.
