How to fix?
org.bouncycastle:bcprov-jdk15on to version 1.56 or higher.
org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.
Affected versions of this package are vulnerable to Information Exposure. The primary engine class used for AES was
AESFastEngine. Due to the highly table driven approach used in the algorithm it turns out that if the data channel on the CPU can be monitored the lookup table accesses are sufficient to leak information on the AES key being used. There was also a leak in
AESEngine although it was substantially less.
