CVE-2016-1000346 (opens in a new tab)How to fix?
Upgrade Debian:unstable bouncycastle to version 1.56-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream bouncycastle package and not the bouncycastle package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
