Description OSIDB Bzimport 2026-09-22 17:29:12 UTC 
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.
