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

  - An attacker can send a notify request that causes a new secondary domain to be added to the bind backend,
    but causes said backend to update its configuration to an invalid one, leading to the backend no longer
    able to run on the next restart, requiring manual operation to fix it. (CVE-2026-33608)

  - An attacker can send a web request that causes unlimited memory allocation in the internal web server,
    leading to a denial of service. The internal web server is disabled by default. (CVE-2026-33257,
    CVE-2026-33260)

  - Incomplete escaping of LDAP queries when running with 8bit-dns enabled allows users to perform queries of
    internal domain subtrees. (CVE-2026-33609)

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-b47d3e7e16 advisory.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A rogue primary server may cause file descriptor exhaustion and eventually a denial of service, when a     PowerDNS secondary server forwards a DNS update request to it. (CVE-2026-33610)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-edc32576bb advisory.
