CVE-2018-20651

Priority
Description
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.
