CWE-476

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.

Affected configurations

• gnu binutils 2.31 • debian debian linux 7.0 • debian debian linux 8.0 • debian debian linux 9.0 • netapp data ontap
