How to fix?

Upgrade Ubuntu:16.04 percona-xtrabackup to version 2.3.7-0ubuntu0.16.04.1 or higher.

NVD Description

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

xbcrypt in Percona XtraBackup before 2.3.6 and 2.4.x before 2.4.5 does not properly set the initialization vector (IV) for encryption, which makes it easier for context-dependent attackers to obtain sensitive information from encrypted backup files via a Chosen-Plaintext attack. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-6394.
