Description D'juan McDonald (domhnall) 2019-01-06 11:17:11 UTC 
(https://nvd.nist.gov/vuln/detail/CVE-2018-20651):
A NULL pointer dereference was discovered in elf_link_add_object_symbols in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31.1. This occurs for a crafted ET_DYN with no program headers. A specially crafted ELF file allows remote attackers to cause a denial of service, as demonstrated by ld.
