Description Alexander Bergmann 2018-06-05 11:34:54 UTC

CVE-2016-1000346

In the Bouncy Castle JCE Provider version 1.55 and earlier the other party DH
public key is not fully validated. This can cause issues as invalid keys can be
used to reveal details about the other party's private key where static
Diffie-Hellman is in use. As of release 1.56 the key parameters are checked on
agreement calculation.
