CVE-2017-15939 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 binutils to version 2.26.1-1ubuntu1~16.04.8+esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, mishandles NULL files in a .debug_line file table, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ELF file, related to concat_filename. NOTE: this issue is caused by an incomplete fix for CVE-2017-15023.
