Ref: https://nvd.nist.gov/vuln/detail/CVE-2017-8395
====================================================
Description

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU
Binutils 2.28, is vulnerable to an invalid write of size 8 because of missing a
malloc() return-value check to see if memory had actually been allocated in the
_bfd_generic_get_section_contents function. This vulnerability causes programs
that conduct an analysis of binary programs using the libbfd library, such as
objcopy, to crash.
