From ${URL} : 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. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
This CVE is not really explanatory: which version is affected? what is the fix? We ship xerces-1.3 and the very latest version available at http://xerces.apache.org/mirrors.cgi, that is 2.11.0. I guess it might affect older versions. The only package relying on xerces-1.3 is castor and it's been marked for removal. I will remove it after castor is removed. Please note that RH closed the bug as WONTFIX: https://bugzilla.redhat.com/show_bug.cgi?id=787104.
