The remote Fedora 40 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-687525fcca advisory.

    # BIND 9.18.19

    ##Security Fixes

    -    Previously, sending a specially crafted message over the control channel could cause the packet-     parsing code to run out of available stack memory, causing named to terminate unexpectedly. This has been     fixed. ([CVE-2023-3341](https://access.redhat.com/security/cve/CVE-2023-3341))
    -    A flaw in the networking code handling DNS-over-TLS queries could cause named to terminate     unexpectedly due to an assertion failure under significant DNS-over-TLS query load. This has been fixed.

The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5504 advisory.

  - The code that processes control channel messages sent to `named` calls certain functions recursively     during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on     the environment, this may cause the packet-parsing code to run out of available stack memory, causing     `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its     contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key;
    only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9     versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through     9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. (CVE-2023-3341)

  - A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly     due to an assertion failure. This happens when internal data structures are incorrectly reused under     significant DNS-over-TLS query load. This issue affects BIND 9 versions 9.18.0 through 9.18.18 and     9.18.11-S1 through 9.18.18-S1. (CVE-2023-4236)

Note that Nessus has not tested for these issues 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-2023-4236 advisory.

  - A flaw in the networking code handling DNS-over-TLS queries may cause  named  to terminate unexpectedly     due to an assertion failure. This happens when internal data structures are incorrectly reused under     significant DNS-over-TLS query load.A  named  instance vulnerable to this flaw may terminate unexpectedly     when subjected to significant DNS-over-TLS query load. This flaw does not affect DNS-over-HTTPS code, as     that uses a different TLS implementation. (CVE-2023-4236)

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6390-1 advisory.

    It was discovered that Bind incorrectly handled certain control channel messages. A remote attacker with     access to the control channel could possibly use this issue to cause Bind to crash, resulting in a denial     of service. (CVE-2023-3341)

    Robert Story discovered that Bind incorrectly handled certain DNS-over-TLS queries. A remote attacker     could possibly use this issue to cause Bind to crash, resulting in a denial of service. This issue only     affected Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-4236)
