In the Bouncy Castle JCE Provider version 1.55 and previous versions 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 malicious user to gain information about the signature's k value and ultimately the private value as well.
