Threats affecting pkg:maven/Apache Software Foundation/org.apache.wss4j:wss4j-ws-security-common

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.

Apache WSS4J versions prior to 4.0.2, 3.0.6, and 2.4.4 improperly validate attacker-controlled derived-key lengths and offsets. This flaw allows the use of cryptographically weak keys or causes excessive CPU and memory consumption when processing crafted WS-Security messages. The issue is fixed by enforcing minimum and maximum key lengths and offset limits. Users should upgrade to fixed versions to mitigate the risk.
