Technical details
A stack exhaustion or uncontrolled recursion vulnerability exists in Apache Neethi's policy parsing logic. When the library processes a WS-Policy that is either deeply nested or lacks mandatory Policy IDs, it enters a recursive loop that consumes excessive system memory. This is a remote, unauthenticated attack vector that allows an attacker to trigger a Denial of Service (DoS) by providing a malicious policy file to any application utilizing the Neethi library for parsing. The issue is resolved in version 3.2.3.
