Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and Red Hat. Impact type from CWE-770.

Summary

A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
