CVE-2018-16403 elfutils: Heap-based buffer over-read in libdw/dwarf_getabbrev.c and libwd/dwarf_hasattr.c causes crash
Elfutils through version 0.173 is vulnerable to a heap-based buffer over-read due to incorrect checks for the end of attribute lists in the libdw/dwarf_getabbrev.c:__libdw_getabbrev() and libdw/dwarf_hasattr.c:dwarf_hasattr() functions. An attacker could exploit this to cause a crash via a crafted ELF.
