How to fix?

Upgrade Ubuntu:14.04 procps to version 1:3.3.9-1ubuntu2.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream procps package and not the procps package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).
