NVD Description

Note: Versions mentioned in the description apply only to the upstream eap8-jackson-modules-base package and not the eap8-jackson-modules-base package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
