The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.30, allows remote attackers to cause a denial of service
(excessive memory allocation and application crash) via a crafted ELF file,
as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc
in libbfd.c. This can occur during execution of nm.
