Overview

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

Affected versions of this package are vulnerable to Timing attacks. Where timings can be closely observed for the generation of signatures, the lack of blinding may allow an attacker to gain information about the signature's k value and ultimately the private value as well.

Remediation

Upgrade org.bouncycastle:bcprov-jdk15on to version 1.56 o higher.
