CVE-2016-6225 (opens in a new tab)How to fix?
There is no fixed version for Debian:8 percona-xtrabackup.
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 Debian.
See How to fix? for Debian:8 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.
