other computers.\n\nSecurity Fix(es):\n\n* avahi: Reachable assertion in avahi_dns_packet_append_record (CVE-2023-38469)\n* avahi: Reachable assertion in avahi_escape_label (CVE-2023-38470)\n* avahi: Reachable assertion in dbus_set_host_name (CVE-2023-38471)\n* avahi: Reachable assertion in avahi_rdata_parse (CVE-2023-38472)\n* avahi: Reachable assertion in avahi_alternative_host_name (CVE-2023-38473)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n\nAdditional Changes:\n\nFor detailed information on changes in this release, see the AlmaLinux Release Notes linked from the References
