The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2720 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.

    The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP     network to get their own network configuration information, including an IP address, a subnet mask, and a     broadcast address. The dhcp packages provide a relay agent and ISC DHCP service required to enable and     administer DHCP on a network.

    Security Fix(es):

    * bind: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)

    * bind: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)

    * bind: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)

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

    * bind: processing large delegations may severely degrade resolver performance (CVE-2022-2795)

    * bind: DNS forwarders - cache poisoning vulnerability (CVE-2021-25220)

    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.
