Ref: https://nvd.nist.gov/vuln/detail/CVE-2017-8393
===================================================
Description

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU
Binutils 2.28, is vulnerable to a global buffer over-read error because of an
assumption made by code that runs for objcopy and strip, that SHT_REL/SHR_RELA
sections are always named starting with a .rel/.rela prefix. This vulnerability
causes programs that conduct an analysis of binary programs using the libbfd
library, such as objcopy and strip, to crash.
