Description Tomas Hoger 2014-10-10 04:47:47 EDT

It was discovered that the StAX XML parser in the JAXP (Java API for XML Processing) component of OpenJDK failed to properly honor setting indicating (defined using isSupportingExternalEntities / IS_SUPPORTING_EXTERNAL_ENTITIES property) whether external XML entities should be processed.  External parameter entities were processed even when the StAX parser was configured to not process external entities.  An attacker able to provide a specially-crafted XML file to an application using StAX parser could use this flaw to perform XML eXternal Entity (XXE) attack.

Comment 1 Tomas Hoger 2014-10-14 16:13:13 EDT

Public now via Oracle Critical Patch Update - October 2014.  Fixed in Oracle Java SE 6u85, 7u71, and 8u25.
