This updated dnsmasq package fixes security issues: Certain DNSSEC aspects of the DNS protocol allow a remote attacker to trigger a denial of service via extreme consumption of resource caused by DNSSEC query or response: - KeyTrap - Extreme CPU consumption in DNSSEC validator. (CVE-2023-50387) - Preparing an NSEC3 closest encloser proof can exhaust CPU resources. (CVE-2023-50868) This update also fixes issues with udp packet size (fix already present in mageia package for 2.89), possible segfault and caching.
