TLS Padding Oracle
Affecting com.madgag.spongycastle:bctls-jdk15on artifact, versions [,1.59)
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.
