Red Hat Security Advisory: bind and bind-dyndb-ldap security update
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.
AI Analysis
Technical Summary
The advisory covers three main vulnerabilities in BIND's DNS server (named) component: CVE-2024-1737 causes the BIND database to slow down significantly if a very large number of resource records exist at the same name; CVE-2024-1975 allows SIG(0) requests to be used to exhaust CPU resources; and CVE-2024-4076 triggers an assertion failure when serving both stale cache data and authoritative zone content simultaneously. These issues affect Red Hat Enterprise Linux 9 and Red Hat OpenShift Container Platform 4.15. Red Hat has issued updated packages and container images to fix these vulnerabilities. The advisory includes detailed instructions for upgrading and references to the official errata and release notes.
Potential Impact
The vulnerabilities can lead to degraded DNS server performance, potential denial of service through CPU exhaustion, and server crashes due to assertion failures. This can impact DNS resolution reliability and availability on affected systems running vulnerable versions of BIND. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released official security updates for affected versions of Red Hat Enterprise Linux 9 and Red Hat OpenShift Container Platform 4.15 that address these vulnerabilities. Users should upgrade to the updated packages and container images as soon as they are available in their respective release channels. Instructions for upgrading OpenShift clusters are provided by Red Hat. No additional mitigation steps are required beyond applying these official fixes.
