It was discovered that the Hotspot component did not properly parse invalid generic attributes for fields and methods. An untrusted Java application or applet could possibly use this flaw to bypass Java sandbox restrictions.

It was discovered that the bytecode verification did not properly prevent ctor calls to this() and super() from certain code constructs. An untrusted Java application or applet could possibly use this flaw to bypass Java sandbox restrictions.

Florian Weimer discovered that AtomicReferenceFieldUpdater in OpenJDK does not properly check if the field to be updated is of primitive type. An untrusted Java application or applet could use flaw to trigger Java virtual machine memory corruption and possibly bypass Java sandbox restrictions.

AtomicReferenceFieldUpdater API documentation: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/atomic/AtomicReferenceFieldUpdater.html

This issue is mitigated by the bug that prevents AtomicFieldUpdater instances when code runs under security manager restrictions under OpenJDK and Oracle JDK 6 and 7. The bug was fixed in JDK8:
