The bfd_cache_close function in bfd/cache.c in the Binary File Descriptor
(BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and
earlier, allows remote attackers to cause a heap use after free and
possibly achieve code execution via a crafted nested archive file. This
issue occurs because incorrect functions are called during an attempt to
release memory. The issue can be addressed by better input validation in
the bfd_generic_archive_p function in bfd/archive.c.
