CVE-2018-18607

Priority
Description
An issue was discovered in elf_link_input_bfd in elflink.c in the Binary
File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils
2.31. There is a NULL pointer dereference in elf_link_input_bfd when used
for finding STT_TLS symbols without any TLS section. A specially crafted
ELF allows remote attackers to cause a denial of service, as demonstrated
by ld.
