"The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple
vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - binutils: heap-based buffer overflow in finish_stab in stabs.c (CVE-2018-12699)

  - binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump,
    bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow
    trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to
    be exploitable via Local. This vulnerability appears to have been fixed in after commit
    3a551c7a1b80fca579461774860574eabfd7f18f. (CVE-2018-1000876)

  - The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab
    entry with a SECTION type that has a 0 value, which allows remote attackers to cause a denial of
    service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy.
    (CVE-2018-10535)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
