The version of AHV installed on the remote host is prior to 11.0.0.2 / AHV-11.0.0.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-11.0.0.2 advisory.

  - A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages     to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized     cipher context. This occurs because the OpenSSL error code returned aliases with the SSH_OK code,     resulting in libssh not properly detecting the error returned by the OpenSSL library. This issue can lead     to undefined behavior, including compromised data confidentiality and integrity or crashes.
    (CVE-2025-5987)

  - 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)

  - ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly     untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted     sources are the command line and %-sequence expansion of a configuration file. (A configuration file that     provides a complete literal username is not categorized as an untrusted source.) (CVE-2025-61984)

  - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code     execution when a ProxyCommand is used. (CVE-2025-61985)

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, an out-of-bounds read     vulnerability exists in png_image_read_composite when processing palette images with     PNG_FLAG_OPTIMIZE_ALPHA enabled. The palette compositing code in png_init_read_transformations incorrectly     applies background compositing during premultiplication, violating the invariant component  alpha  257     required by the simplified PNG API. This issue has been patched in version 1.6.51. (CVE-2025-64720)

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