Synopsis

The remote Red Hat host is missing one or more security updates for bind9.16.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:5525 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL bind9.16 package based on the guidance in RHSA-2024:5525.
