Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the XmlTreeBuilder namespace scope tracking when parsing untrusted XML input. A remote attacker can supply a deeply nested XML document with uniquely named namespace declarations to cause a denial of service.
