How to fix?

There is no fixed version for org.bouncycastle:bcprov-jdk15on.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Observable Timing Discrepancy via the PKCS#1 1.5 and OAEP decryption process. An attacker can recover ciphertexts via a side-channel attack by exploiting the Marvin security flaw. The PKCS#1 1.5 attack vector leaks data via javax.crypto.Cipher exceptions and the OAEP interface vector leaks via the bit size of the decrypted data.
