Published Aug 14, 2024 · Updated Oct 29, 2026

Ecosystem: AlmaLinux

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

    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…
