The remote Scientific Linux host is missing one or more security
A flaw was found in the way the Avahi daemon (avahi-daemon) processed
Multicast DNS (mDNS) packets with corrupted checksums. An attacker on
the local network could use this flaw to cause avahi-daemon on a
target system to exit unexpectedly via specially crafted mDNS packets.
A flaw was found in the way avahi-daemon processed incoming unicast
mDNS messages. If the mDNS reflector were enabled on a system, an
attacker on the local network could send a specially crafted unicast
mDNS message to that system, resulting in its avahi-daemon flooding
the network with a multicast packet storm, and consuming a large
amount of CPU. Note: The mDNS reflector is disabled by default.
After installing the update, avahi-daemon will be restarted
