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

  - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has a
    swap_std_reloc_out function in bfd/aoutx.h that is vulnerable to an invalid read (of size 4) because of
    missing checks for relocs that could not be recognised. This vulnerability causes Binutils utilities like
    strip to crash. (CVE-2017-7302)

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