The Binary File Descriptor (BFD) library (aka libbfd) has a swap_std_reloc_out function in bfd/aoutx.h that is vulnerable to an invalid read (of size 4) because of missing checks for relocs that could not be recognised. This vulnerability causes Binutils utilities like strip to crash. Upstream bug: https://sourceware.org/bugzilla/show_bug.cgi?id=20921
