How to fix?

Upgrade BouncyCastle to version 1.8.1 or higher.

Overview

BouncyCastle is a C# implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Cryptographic Issues. The TLS implementation does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
