medium Nessus Plugin ID 175448

Language:

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-2023:2261 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: processing large delegations may severely degrade resolver performance (CVE-2022-2795)

* bind: flooding with UPDATE requests may lead to DoS (CVE-2022-3094)

* bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3736)

* bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3924)
