Description Tomas Hoger 2016-07-15 13:33:55 UTC

It was discovered that the JAXP component of OpenJDK did not place a limit on the number of entity replacements performed 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.

Updates correcting this issue address the problem by introducing a limit on the number of entity replacements that can be performed.  The limit can be controlled using the jdk.xml.entityReplacementLimit system property.

Comment 1 Tomas Hoger 2016-07-20 07:44:50 UTC

Public now via Oracle CPU July 2016, fixed in Oracle JDK 8u101, 7u111, and 6u121.
