Description Tomas Hoger 2016-07-15 13:19:17 UTC
It was discovered that the JAXP component of OpenJDK did not enforce the maximum XML name limit (jdk.xml.MaxXMLNameLimit) when parsing namespace URIs in 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 2016-07-20 07:44:39 UTC
Public now via Oracle CPU July 2016, fixed in Oracle JDK 8u101, 7u111, and 6u121.
