How to fix?

Upgrade Ubuntu:16.04 libice to version 2:1.0.9-1ubuntu0.16.04.1+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libice package and not the libice package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

It was discovered that libICE before 1.0.9-8 used a weak entropy to generate keys. A local attacker could potentially use this flaw for session hijacking using the information available from the process list.
