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. (CVE-2012-1682)

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.

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
