There is no fixed version for Echo:latest wss4j.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wss4j package and not the wss4j package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes this while resolving the signature's key reference, before the message is authenticated, so an eleven-byte extension triggers a 2 GB allocation. Repeated requests exhaust server memory. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
