RLSA-2026:24368

Synopsis

Important: bind9.18 security update

Description

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating properly.

Security Fix(es):

* bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation (CVE-2026-3039)

* bind: BIND: Denial of Service via specially crafted DNS messages (CVE-2026-5946)

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.
