CVE-2017-7299 is a medium-severity denial of service vulnerability in Gnu Binutils, published on 29 Mar 2017. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an invalid read (of size 8) because the code to emit relocs (bfd_elf_final_link function in bfd/elflink.c) does not check the format of the input file before trying to read the ELF reloc section header. The vulnerability leads to a GNU linker (ld) program crash.
