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

  - A vulnerability, which was classified as problematic, has been found in GNU Binutils 2.45. Affected by
    this issue is the function bfd_elf_set_group_contents of the file bfd/elf.c. The manipulation leads to
    out-of-bounds write. It is possible to launch the attack on the local host. The exploit has been disclosed
    to the public and may be used. The name of the patch is 41461010eb7c79fee7a9d5f6209accdaac66cc6b. It is
    recommended to apply a patch to fix this issue. (CVE-2025-7546)

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