How to fix?

Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.66 or higher.


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

Affected versions of this package are vulnerable to Timing Attack. A timing issue within the EC math library can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures.
