libdw/dwarf_getaranges.c:dwarf_getaranges() via crafted file
(CVE-2018-16062)

* elfutils: Double-free due to double decompression of sections in crafted
ELF causes crash (CVE-2018-16402)

* elfutils: Heap-based buffer over-read in libdw/dwarf_getabbrev.c and
libwd/dwarf_hasattr.c causes crash (CVE-2018-16403)
