Description Kurt Seifried 2012-02-03 07:05:28 UTC
Juraj Somorovsky reported that certain XML parsers/servers are affected by the same, or similar, flaw as the hash table collisions CPU usage denial of service. Sending a specially crafted message to an XML service can result in longer processing time, which could lead to a denial of service. It is reported that this attack on XML can be applied on different XML nodes (such as entities, element attributes, namespaces, various elements in the XML security, etc.). xerces-j2 is written in Java and makes significant use of arrays.
