Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in Wildfly's implementation of Xerces, specifically in the way the XMLSchemaValidator class in the JAXP component of Wildfly enforced the "use-grammar-pool-only" feature. A remote attacker can pass specially-crafted XML file to the application and manipulate the validation process in certain cases.
