RHEL 9 : bind (RHSA-2022:6763)

high Nessus Plugin ID 165637

Synopsis

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

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:6763 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: BIND 9 resolvers configured to answer from cache with zero stale-answer-timeout may terminate unexpectedly (CVE-2022-3080)

* bind: memory leak in ECDSA DNSSEC verification code (CVE-2022-38177)

* bind: memory leaks in EdDSA DNSSEC verification code (CVE-2022-38178)

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 bind package based on the guidance in RHSA-2022:6763.
