NVD Description
Note: Versions mentioned in the description apply only to the upstream bouncycastle package and not the bouncycastle package as distributed by Ubuntu.
BouncyCastle TLS prior to version 1.0.3, when configured to use the JCE (Java Cryptography Extension) for cryptographic functions, provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable application. This vulnerability is referred to as "ROBOT."
