Overview
org.wildfly.security:wildfly-elytron is a new WildFly sub-project which is completely replacing the combination of PicketBox and JAAS as the WildFly client and server security mechanism.
Affected versions of this package are vulnerable to Timing Attack. Currently org.wildfly.security.mechanism.scram.ScramServer uses simple byte comparison to verify the message nonce and client proof. Simple byte comparison returns on the first mismatch and is therefore susceptible to timing attacks.
