The version of AOS installed on the remote host is prior to 7.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.6 advisory.

  - NLnet Labs Unbound 1.19.1 up to and including version 1.25.0 has a vulnerability in the DNSSEC validator     that enables denial of service and possible remote code execution as a result of deep copying a data     structure and erroneously overwriting a destination pointer. An adversary can exploit the vulnerability by     controlling a malicious signed zone and querying a vulnerable Unbound. When DS sub-queries need to suspend     validation due to NSEC3 computational budget exhaustion (introduced in Unbound 1.19.1), Unbound deep-     copies response messages to preserve them across memory region teardown. A struct-assignment bug     overwrites the destination's pointer with the source's pointer. After the sub-query region is freed, the     resumed validator dereferences this dangling pointer, triggering a crash or potentially enabling arbitrary     code execution. Unbound 1.25.1 contains a patch with a fix to preserve the correct pointer when deep     copying the data structure. (CVE-2026-33278)

  - A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in     the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow.
    The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The     identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended     to deploy a patch. The code maintainer replied with [f]ixed for 2.46. (CVE-2025-11083)

  - A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in     the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable     characters (which would need escaping), the calculation of the length of the escaped string could     overflow, leading to a potential write off the end of the newly allocated string. (CVE-2025-13601)

  - A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in     grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be     leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention     of secure boot protections. (CVE-2024-45777)

  - In Sudo through 1.9.17p2 before 3e474c2, a failure of a setuid, setgid, or setgroups call, during a     privilege drop before running the mailer, is not a fatal error and can lead to privilege escalation.
    (CVE-2026-35535)

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

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-7982f70f74 advisory.

    Notable changes from the rebase:
    * pkcs11: Update PKCS11 headers to version 3.2
    * rpc: fix NULL dereference via C_DeriveKey with specific NULL parameters (CVE-2026-2100)
    * trust: Lookup DNs in reverse order (RFC4514 section 2.1)

Tenable has extracted the preceding description block directly from the Fedora security advisory.
