The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid read (of size 4) because of missing a check (in the find_link function) for null headers before attempting to match them. This vulnerability causes Binutils utilities like strip to crash. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-7303
