Description Stefan Cornelius 2014-04-14 10:16:24 UTC

It was discovered that the System.arraycopy() method has a race
condition between verifying source elements and storing them. An
untrusted Java application or applet could possibly use this flaw to
trigger a Java Virtual Machine memory corruption.
