Package        : bouncycastle
CVE ID         : CVE-2018-1000180

It was discovered that the low-level interface to the RSA key pair
generator of Bouncy Castle (a Java implementation of cryptographic
algorithms) could perform less Miller-Rabin primality tests than
expected.

For the stable distribution (stretch), this problem has been fixed in
version 1.56-1+deb9u2.

We recommend that you upgrade your bouncycastle packages.

For the detailed security status of bouncycastle please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/bouncycastle
