"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-680 advisory.

    Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same
    hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and
    also when handling client queries for this name.This issue affects BIND 9 versions 9.11.0 through 9.11.37,
    9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.4-S1 through 9.11.37-S1,
    9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.27-S1. (CVE-2024-1737)

    If a server hosts a zone containing a KEY Resource Record, or a resolver DNSSEC-validates a KEY
    Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by
    sending a stream of SIG(0) signed requests.This issue affects BIND 9 versions 9.0.0 through 9.11.37,
    9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.9.3-S1 through 9.11.37-S1,
    9.16.8-S1 through 9.16.49-S1, and 9.18.11-S1 through 9.18.27-S1. (CVE-2024-1975)

    Client queries that trigger serving stale data and that also require lookups in local authoritative zone
    data may result in an assertion failure.This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0
    through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through 9.11.37-S1, 9.16.13-S1 through 9.16.50-S1, and
    9.18.11-S1 through 9.18.27-S1. (CVE-2024-4076)
