There is no fixed version for org.bouncycastle:bcprov-debug-jdk15on.
Overview
org.bouncycastle:bcprov-debug-jdk15on is a Java implementation of cryptographic algorithms.
Affected versions of this package are vulnerable to Improper Certificate Validation in the check() method of ProvOcspRevocationChecker, which verifies a stapled OCSP response's signature and then treats the certificate as unrevoked when no SingleResponse entry matches its CertID, without requiring a binding match. An attacker can present a revoked certificate that BC-based clients accept as valid by stapling any legitimately signed OCSP response from the same CA, such as a good response for a different serial number. This applies when the client uses BC revocation checking with the response supplied through the stapled PKIXRevocationChecker.setOcspResponses() path rather than fetched over the network, and the response must be validly signed by the same issuer.
