SNYK-JAVA-ORGBOUNCYCASTLE-6277381 - Observable Timing Discrepancy in org.bouncycastle:bcprov-jdk18on
org.bouncycastle:bcprov-jdk18on
Introduced through: org.keycloak:keycloak-quarkus-server-deployment@999.0.0-SNAPSHOT › org.keycloak:keycloak-quarkus-server@999.0.0-SNAPSHOT › org.keycloak:keycloak-crypto-default@999.0.0-SNAPSHOT › org.bouncycastle:bcprov-jdk18on@1.77

Overview

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.

Remediation

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