"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has binutils packages installed that are affected
by multiple vulnerabilities:

  - An issue was discovered in arm_pt in cplus-dem.c in GNU
    libiberty, as distributed in GNU Binutils 2.30. Stack
    Exhaustion occurs in the C++ demangling functions
    provided by libiberty, and there are recursive stack
    frames: demangle_arm_hp_template, demangle_class_name,
    demangle_fund_type, do_type, do_arg, demangle_args, and
    demangle_nested_args. This can occur during execution of
    nm-new. (CVE-2018-12641)

  - A NULL pointer dereference (aka SEGV on unknown address
    0x000000000000) was discovered in
    work_stuff_copy_to_from in cplus-dem.c in GNU libiberty,
    as distributed in GNU Binutils 2.30. This can occur
    during execution of objdump. (CVE-2018-12697)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
