CVE-2017-7300

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h
that is vulnerable to a heap-based buffer over-read (off-by-one) because of
an incomplete check for invalid string offsets while loading symbols,
leading to a GNU linker (ld) program crash.
