Debian DSA-4233-1 : bouncycastle - security update

Medium Nessus Plugin ID 110665

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the bouncycastle packages.

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