Weak Private Key Generation in Bouncy Castle JCE Provider 1.55 and Earlier

CVE-2016-1000343 · MEDIUM Severity

AV:N/AC:L/AU:N/C:P/I:N/A:N

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.
