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.

CVE-2018-19932 GNU binutils vulnerabilities
Title: GNU binutils vulnerabilities
Summary: Several security issues were fixed in GNU binutils.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
It was discovered that GNU binutils contained a large number of security
issues. If a user or automated system were tricked into processing a
specially-crafted file, a remote attacker could cause GNU binutils to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
Instructions: In general, a standard system update will make all the necessary changes.

binutils: NULL pointer dereference in elf_link_input_bfd in elflink.c

CVE-2018-18607 [MEDIUM] CWE-476 binutils: NULL pointer dereference in elf_link_input_bfd in elflink.c
binutils: NULL pointer dereference in elf_link_input_bfd in elflink.c
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.
Statement: Red Hat has determined this flaw to be of low impact as successful exploitation results in a crash (denial of service) of the application utilizing the binutils library and does not impact system-wide stability or lead to arbitrary code execution or memory corruption.
