  - 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)
