Description Marcus Meissner 2018-06-04 15:30:59 UTC

CVE-2016-1000343

In the Bouncy Castle JCE Provider version 1.55 and earlier the DSA key pair
generator generates a weak private key if used with default values. If the JCA
key pair generator is not explicitly initialised with DSA parameters, 1.55 and
earlier generates a private value assuming a 1024 bit key size. In earlier
releases this can be dealt with by explicitly passing parameters to the key pair
generator.
