CVE-2024-30171 - Observable Discrepancy in org.bouncycastle:bcprov-jdk18on
org.bouncycastle:bcprov-jdk18on
Introduced through: org.keycloak:keycloak-operator@999.0.0-SNAPSHOT › org.bouncycastle:bcprov-jdk18on@1.77

Overview

Affected versions of this package are vulnerable to Observable Discrepancy due to the timing difference between exceptions thrown when processing RSA key exchange handshakes, AKA Marvin.

Note: The implemented fix mitigates the leakage of data via the PKCS#1 interface, but does not fully alleviate the side-channel as it allows cases in which the padding check fails but the handshake succeeds.

Remediation

Upgrade org.bouncycastle:bcprov-jdk18on to version 1.78 or higher.
