Description Tomas Hoger 2016-10-16 20:54:10 UTC 
It was discovered that the Hotspot component of OpenJDK did not check types of System.arraycopy() function arguments src and dest in certain cases.  An untrusted Java application or applet could use this flaw to corrupt virtual machine's memory and bypass Java sandbox restrictions.
