In the Bouncy Castle JCE Provider version 1.55 and earlier ECDSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of 'invisible' data into a signed structure.

En Bouncy Castle JCE Provider en versiones 1.55 y anteriores, el ECDSA no valida completamente el cifrado ASN.1 de la firma en verificación. Es posible inyectar elementos extra en la secuencia que forma la firma y, aún así, validarla. En algunos casos, esto podría permitir la introducción de datos "invisibles" en una estructura firmada.
