Description:
 The _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the
 Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU
 Binutils 2.30, processes a negative Data Directory size with an unbounded
 loop that increases the value of (external_IMAGE_DEBUG_DIRECTORY) *edd so
 that the address exceeds its own memory region, resulting in an
 out-of-bounds memory write, as demonstrated by objcopy copying private info
 with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c.
