RLSA-2024:2551

Synopsis

Important: bind security update

Description

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: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)

* bind: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)

* bind: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)

* bind: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution (CVE-2023-5679)

* bind: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled (CVE-2023-5517)

* bind: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)

Bug Fix(es):

* bind-dyndb-ldap: rebuilt to adapt ABI changes in bind
