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_dns_packet_append_record (CVE-2023-38469)
  • avahi: Reachable assertion in avahi_escape_label (CVE-2023-38470)
  • avahi: Reachable assertion in dbus_set_host_name (CVE-2023-38471)
  • avahi: Reachable assertion in avahi_rdata_parse (CVE-2023-38472)
  • avahi: Reachable assertion in avahi_alternative_host_name (CVE-2023-38473)
