Summary
Security update for avahi
Details

This update for avahi fixes the following issues:

  • CVE-2025-59529: local DoS due to simple protocol server ignoring client limit CLIENTS_MAX (bsc#1255451).

Changes for avahi:

  • Make /var/lib/avahi-autoipd a ghost dir instead of packaging it since avahi-autoipd creates it on start (jsc#PED-14836).
  • Use libalternative instead of update-alternatives in TW and SLFO (jsc#PED-14835).
