Summary
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
Security Fix(es):
* bind: bind9: BIND's database will be slow if a very large number of RRs exist at the same nam (CVE-2024-1737)
* bind9: bind: SIG(0) can be used to exhaust CPU resources (CVE-2024-1975)
* bind: bind9: Assertion failure when serving both stale cache data and authoritative zone content (CVE-2024-4076)

High 7.5
BIND's database will be slow if a very large number of RRs exist at the same name
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 iss…

High 7.5
SIG(0) can be used to exhaust CPU resources
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 aff…

High 7.5
Assertion failure when serving both stale cache data and authoritative zone content
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.…
