Description

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, miscalculates DW_FORM_ref_addr die refs in the case of a relocatable object file, which allows remote attackers to cause a denial of service (find_abstract_instance_name invalid memory read, segmentation fault, and application crash).
