There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to
    clean up the database. It uses several methods, including some that are asynchronous: a small chunk of
    memory pointing to the cache element that can be cleaned up is first allocated and then queued for later
    processing. It was discovered that if the resolver is continuously processing query patterns triggering
    this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely
    manner. This in turn enables the list of queued cleanup events to grow infinitely large over time,
    allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9
    versions 9.16.0 through 9.16.45 and 9.16.8-S1 through 9.16.45-S1. (CVE-2023-6516)

  - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive
    CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative
    servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through
    9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1
    through 9.18.21-S1. (CVE-2023-4408)

  - A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: -
    `nxdomain-redirect <domain>;` is configured, and - the resolver receives a PTR query for an RFC 1918
    address that would normally result in an authoritative NXDOMAIN response. This issue affects BIND 9
    versions 9.12.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.8-S1 through
    9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1. (CVE-2023-5517)

  - A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure
    during recursive resolution, when both of these features are enabled. This issue affects BIND 9 versions
    9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through 9.16.45-S1,
    and 9.18.11-S1 through 9.18.21-S1. (CVE-2023-5679)

  - If a resolver cache has a very large number of ECS records stored for the same name, the process of
    cleaning the cache database node for this name can significantly impair query performance. This issue
    affects BIND 9 versions 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through
    9.18.21-S1. (CVE-2023-5680)

The version of bind installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-5680 advisory.

  - If a resolver cache has a very large number of ECS records stored for the same name, the process of     cleaning the cache database node for this name can significantly impair query performance. This issue     affects BIND 9 versions 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through     9.18.21-S1. (CVE-2023-5680)

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

The version of ISC BIND installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cve-2023-5680 advisory.
