CyberRota Analysis
AI-GeneratedAn integer overflow vulnerability in WSS4J allows unauthenticated attackers to exploit oversized allocations by sending specially crafted SOAP messages containing X.509 certificates, leading to excessive memory consumption and potential denial of service. Affected users, particularly those utilizing WSS4J for web services security, should prioritize upgrading to versions 4.0.2, 3.0.6, or 2.4.4 to mitigate this high-severity risk.
Original NVD Description
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.
