In affected applications that use the vulnerable local cryptography path, specially crafted encrypted input may bypass integrity verification checks. Operations delegated to the Key Vault service are not affected. The issue is addressed in version 4.10.6."

En aplicaciones afectadas que utilizan la ruta de criptografía local vulnerable, una entrada cifrada especialmente diseñada puede eludir las comprobaciones de verificación de integridad. Las operaciones delegadas al servicio Key Vault no se ven afectadas. El problema se aborda en la versión 4.10.6."
