Descriptions
In the Bouncy Castle JCE Provider version 1.55 and earlier DSA signature generation is vulnerable to timing attack. Where timings can be closely observed for the generation of signatures, the lack of blinding in 1.55, or earlier, may allow an attacker to gain information about the signature's k value and ultimately the private value as well.
En Bouncy Castle JCE Provider, en versiones 1.55 y anteriores, la generación de firmas DSA es vulnerable a ataques de sincronización. En los casos en los que se puede observar detenidamente la sincronización para la generación de firmas, la falta de blindaje en las versiones 1.55 o anteriores puede permitir que un atacante obtenga información sobre el valor k de la firma y, en última instancia, también del valor privado.
