CVE-2018-18607 (opens in a new tab)How to fix?
There is no fixed version for Debian:9 binutils.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
