Description David Jorm 2014-02-14 05:31:20 UTC

It was found that Restlet applications which use XMLRepresentation or XML serializers, as provided by various extensions, are vulnerable to XML entity expansion attacks. A remote attacker could use this flaw to perform a denial of service attack through CPU or memory exhaustion.
