It was discovered that Apache CXF JAX-RS services, via the SamlHeaderInHandler implementation, incorrectly handled invalid SAML tokens provided in authorization headers of requests. A remote attacker can trigger an infinite loop by providing specially crafted values in authorization headers leading to a Denial of Service attack.
Created cxf tracking bugs for this issue:
