The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200904-10
(Avahi: Denial of Service)
Rob Leslie reported that the
originates_from_local_legacy_unicast_socket() function in
avahi-core/server.c does not account for the network byte order of a
port number when processing incoming multicast packets, leading to a
multicast packet storm.
A remote attacker could send specially crafted legacy unicast mDNS
query packets to the Avahi daemon, resulting in a Denial of Service due
to network bandwidth and CPU consumption.
There is no known workaround at this time.
