CVE-2017-7303
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.22%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
