Descriptions

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.

xbcrypt en Percona XtraBackup en versiones anteriores a 2.3.6 y 2.4.x en versiones anteriores a 2.4.5 no establece apropiadamente el vector de inicialización (IV) para cifrado, lo que hace más fácil a atacantes dependientes del contexto obtener información sensible de archivos backup cifrados a través de un ataque de texto plano escogido. NOTA: esta vulnerabilidad existe debido a una corrección incompleta para CVE-2013-6394.
