Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion via schema-model construction in SchemaBuilder. An attacker can cause a stack overflow and denial of service by supplying a deeply nested schema or a chain of nested include, import, or redefine documents that XmlSchemaCollection.read(...) processes. This requires the application to process attacker-controlled schema content.
