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.

The find_nearest_line function in addr2line in GNU Binutils 2.28 does not handle the case where the main file name and the directory name are both empty, triggering a NULL pointer dereference and an invalid write, and leading to a program crash.
