Upgrade Debian:unstable bouncycastle to version 1.51-1 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.

The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman (ECDH) key exchanges, aka an "invalid curve attack."
