Upgrade Ubuntu:14.04 less to version 458-2ubuntu0.1~esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream less package and not the less package as distributed by Ubuntu.
See How to fix? for Ubuntu:14.04 relevant fixed versions and status.
less through 653 allows OS command execution via a newline character in the name of a file, because quoting is mishandled in filename.c. Exploitation typically requires use with attacker-controlled file names, such as the files extracted from an untrusted archive. Exploitation also requires the LESSOPEN environment variable, but this is set by default in many common cases.
