Red Hat Security Advisory 2012-1222-01 - These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. It was discovered that the Beans component in OpenJDK did not perform permission checks properly. An untrusted Java application or applet could use this flaw to use classes from restricted packages, allowing it to bypass Java sandbox restrictions. A hardening fix was applied to the AWT component in OpenJDK, removing functionality from the restricted SunToolkit class that was used in combination with other flaws to bypass Java sandbox restrictions.
