    ## Security Fixes

    -    A malicious DNS client that sent many queries over TCP but never read the responses could cause a
    server to respond slowly or not at all for other clients. This has been fixed. (CVE-2024-0760) [GL #4481]

    -    It is possible to craft excessively large resource records sets, which have the effect of slowing
    down database processing. This has been addressed by adding a configurable limit to the number of records
    that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned
    with the new max-records-per-type option. [GL #497] [GL #3405]

        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 adding a configurable
    limit to the number of records that can be stored per name and type in a cache or zone database. The
    default is 100, which can be tuned with the new max-types-per-name option. (CVE-2024-1737) [GL #3403]

        ISC would like to thank Toshifumi Sakaguchi who independently discovered and responsibly reported the
    issue to ISC. [GL #4548]

    -    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. (CVE-2024-1975) [GL #4480]

    -    Due to a logic error, lookups that triggered serving stale data and required lookups in local
    authoritative zone data could have resulted in an assertion failure. This has been fixed. (CVE-2024-4076)
    [GL #4507]

    Potential data races were found in our DoH implementation, related to HTTP/2 session object management and
    endpoints set object management after reconfiguration. These issues have been fixed. [GL #4473]

    ISC would like to thank Dzintars and Ivo from nic.lv for bringing this to our attention.

    - When looking up the NS records of parent zones as part of looking up DS records, it was possible for
    named to trigger an assertion failure if serve-stale was enabled. This has been fixed. [GL #4661]
