Overview
Affected versions of this package are vulnerable to Asymmetric Resource Consumption (Amplification) through the processing of signed XML data, where input-depth and operation-count limits are not properly enforced, DTD processing is not prohibited by default, and entity references and encrypted-data candidate processing are insufficiently bounded. An attacker can cause excessive resource consumption leading to service disruption by submitting specially crafted XML payloads.
