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.

CVE-2015-6644 Bouncy Castle vulnerabilities
Title: Bouncy Castle vulnerabilities
Summary: Several security issues were fixed in Bouncy Castle.
It was discovered that Bouncy Castle incorrectly handled certain crypto
algorithms. A remote attacker could possibly use these issues to obtain
sensitive information, including private keys.
Instructions: In general, a standard system update will make all the necessary changes.
