Description Tomas Hoger 2016-10-17 14:49:08 UTC 
It was discovered that the ClassLoaderWithRepository class in the JMX component of OpenJDK did not sufficiently perform classloader consistency checks, allowing classloader to return class with different name than requested.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
Comment 1 Tomas Hoger 2016-10-18 20:10:15 UTC 
Public now via Oracle CPU October 2016, fixed in Oracle JDK 8u111, 7u121, and 6u131.
