Description Tomas Hoger 2015-10-20 20:38:44 UTC
It was discovered that the JAXP component of OpenJDK did not enforce the maximum XML name limit (jdk.xml.MaxXMLNameLimit) when parsing XML files.  A specially crafted XML document could cause a Java application using JAXP to consume an excessive amount of memory and CPU time when parsed.

Comment 1 Tomas Hoger 2015-10-21 08:55:33 UTC
Public now via Oracle Critical Patch Update - October 2015.  Fixed in Oracle Java SE 6u105, 7u91, and 8u65.

While this issue affects the JAXP libraries used by EAP, it's possible to
override them with the patched ones from the JDK using the instructions

Comment 17 Jason Shepherd 2016-01-14 04:21:59 UTC
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.
