Summary
Moderate: avahi security update
Details

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: Local DoS by event-busy-loop from writing long lines to /run/avahi-daemon/socket (CVE-2021-3468)
  • avahi: reachable assertion in avahi_s_host_name_resolver_start when trying to resolve badly-formatted hostnames (CVE-2021-3502)
  • avahi: avahi-daemon can be crashed via DBus (CVE-2023-1981)
