Red Hat Product Errata RHSA-2009:0013 0 normal SHIPPED_LIVE Moderate: avahi security update 2009-01-12 14:09:09 UTC

Description Tomas Hoger 2008-12-11 11:05:57 UTC 
Hugo Dias of the Synchron Security Labs discovered a remote denial of service flaw in the avahi daemon.  A crafted multicast DNS (mDNS) packet with source port 0 can trigger assertion in originates_from_local_legacy_unicast_socket() function in avahi-core/server.c -- assert(port > 0); -- causing the daemon to call abort() and exit unexpectedly.

Scope of this attack is usually limited to a single LAN.
