How to fix?

Upgrade Ubuntu:14.04 cpio to version 2.11+dfsg-1ubuntu1.2+esm1 or higher.

NVD Description

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

In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives. When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system.
