The _bfd_elf_parse_attributes function in elf-attrs.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (_bfd_elf_attr_strdup heap-based buffer over-read and application crash) via a crafted ELF file.
The product reads data past the end, or before the beginning, of the intended buffer.
