Description

It is possible to bypass the maximum number of normalized policy alternatives that was introduced in Apache Neethi 3.2.2 via certain crafted policies, which may lead to a denial of service attack via resource consumption. Users are recommended to upgrade to version 3.2.3, which fixes this issue.
