untangle is a python library to convert XML data to python objects. untangle versions 1.2.0 and earlier improperly restricts recursive entity references in DTDs. By exploiting this vulnerability, a remote unauthenticated attacker may cause a denial-of-service (DoS) condition on the server where the product is running.
The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.
