Summary
Apache Neethi: Crafted policies cause unbounded work during intersection leading to denial of service
Details

A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
