CVE-2016-1000343

bouncycastle: DSA key pair generator generates a weak private key by default

Published Jun 4, 2018 CVSS 3.0 · 7.5 High EPSS 3.2% KEV · Not listed
Description
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.
