RedHat: RHSA-2020-1176:01 Low: avahi security update
Summary
Avahi is an implementation of the DNS Service Discovery and Multicast DNS
specifications for Zero Configuration Networking. It facilitates service
discovery on a local network. Avahi and Avahi-aware applications allow you
to plug your computer into a network and, with no configuration, view other
people to chat with, view printers to print with, and find shared files on
other computers.
Security Fix(es):
* avahi: Multicast DNS responds to unicast queries outside of local network
(CVE-2017-6519)
