It was discovered that the Security component of OpenJDK did not restrict which classes could be used when deserializing keys form the JCEKS key stores. A specially crafted JCEKS key store could possibly use this flaw to execute arbitrary code with the privileges of an application reading data form the key store.

The fix adds support for a new security property jceks.key.serialFilter which can be used to specify classes that can be used when deserializing data from the JCEKS key stores.

A flaw was found in the way the Hotspot component of OpenJDK handled clones of the java.lang.ref.Reference objects. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.
