Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:60383 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.

* bind: bind9: Unexpected exit with NSEC and NSEC3 both present (CVE-2026-13204)

* bind: bind9: Incorrect acceptance of NSEC3 records (CVE-2026-10723)
