Scientific Linux Security Update : avahi on SL5.x i386/x86_64

Medium Nessus Plugin ID 61017


The remote Scientific Linux host is missing one or more security updates.


A flaw was found in the way the Avahi daemon (avahi-daemon) processed Multicast DNS (mDNS) packets with an empty payload. An attacker on the local network could use this flaw to cause avahi-daemon on a target system to enter an infinite loop via an empty mDNS UDP packet.

After installing the update, avahi-daemon will be restarted automatically.


Update the affected packages.
