Red Hat Bugzilla – Bug 1273645
CVE-2015-4911 OpenJDK: incomplete supportDTD enforcement (JAXP, 8130078)
Last modified: 2016-01-13 23:25:34 EST
It was discovered that the StAX XML parser in the JAXP component of OpenJDK could do certain DTD processing even when DTD support was disabled via the javax.xml.stream.supportDTD system property. A specially crafted XML document could cause a Java application using JAXP to consume an excessive amount of memory and CPU time when parsed.
Public now via Oracle Critical Patch Update - October 2015. Fixed in Oracle Java SE 6u105, 7u91, and 8u65. External References: http://www.oracle.com/technetwork/topics/security/cpuoct2015-2367953.html#AppendixJAVA

Closed the EAP trackers as won't fix because the issue was ranked as moderate and there is a workaround. The workaround is to use your own JAXP libraries by packaging them with your application. https://access.redhat.com/solutions/874723
