RHSA-2024:1800 - Important: bind and bind-dyndb-ldap security updates
Synopsis
Important: bind and bind-dyndb-ldap security updates
Type/Severity
Security Advisory Important
Topic
Updates for bind and bind-dyndb-ldap are now available for Red Hat Enterprise Linux 9.0 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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.
Bind-dyndb-ldap provides an LDAP back-end plug-in for BIND. It features support for dynamic updates and internal caching, to lift the load off of your LDAP server.
Security Fix(es):
-
bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)
-
bind9: Querying RFC 1918 reverse zones may cause an assertion failure when "nxdomain-redirect" is enabled (CVE-2023-5517)
-
bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution (CVE-2023-5679)
-
bind9: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)
-
bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)
-
bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)
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.
