CVE-2015-4911
First published: Tue Oct 20 2015(Updated: )
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.
