Security issues fixed:

  * It is possible to craft excessively large numbers of resource record types
    for a given owner name, which has the effect of slowing down database
    processing. This has been addressed by only allowing a maximum of 100
    records to be stored per name and type in a cache or zone database.
    (CVE-2024-1737, bsc#1228256)
  * Validating DNS messages signed using the SIG(0) protocol (RFC 2931) could
    cause excessive CPU load, leading to a denial-of-service condition. Support
    for SIG(0) message validation was removed from this version of named.
