dwarf_macro5.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (NULL pointer dereference) via a debugging information entry using DWARF5 and without a DW_AT_name.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
