It was found that the JAXP component of OpenJDK failed to correctly enforce parse tree size limits when parsing XML document. An attacker able to make a Java application parse a specially crafted XML document could use this flaw to make it consume an excessive amount of CPU and memory.

Description Tomas Hoger 2017-04-18 21:51:57 UTC 
It was found that the JAXP (Java API for XML Processing) component of OpenJDK failed to correctly enforce parse tree size limits when parsing XML document.  An attacker able to make a Java application parse a specially crafted XML document could use this flaw to make it consume an excessive amount of CPU and memory.
Comment 1 Tomas Hoger 2017-04-18 22:19:07 UTC 
Public now via Oracle CPU April 20167, fixed in Oracle JDK 8u131, 7u141, and 6u151.
