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)

  - Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in     Vim's tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar archives.
    Impact is low because this exploit requires direct user interaction. However, successfully exploitation     can lead to overwriting sensitive files or placing executable code in privileged locations, depending on     the permissions of the process editing the archive. The victim must edit such a file using Vim which will     reveal the filename and the file content, a careful user may suspect some strange things going on.
    Successful exploitation could results in the ability to execute arbitrary commands on the underlying     operating system. Version 9.1.1552 contains a patch for the vulnerability. (CVE-2025-53905)

  - Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in     Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives.
    Impact is low because this exploit requires direct user interaction. However, successfully exploitation     can lead to overwriting sensitive files or placing executable code in privileged locations, depending on     the permissions of the process editing the archive. The victim must edit such a file using Vim which will     reveal the filename and the file content, a careful user may suspect some strange things going on.
    Successful exploitation could results in the ability to execute arbitrary commands on the underlying     operating system. Version 9.1.1551 contains a patch for the vulnerability. (CVE-2025-53906)

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

  - A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central     Processing Unit) and memory consumption via specially crafted malicious certificates containing a large     number of name constraints and subject alternative names (SANs). (CVE-2025-14831)

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

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:6737 advisory.
