Details

properly prevent access to restricted classes. A remote attacker could
use this to create an untrusted Java applet or application that would
bypass Java sandbox restrictions. (CVE-2012-1682)

It was discovered that functionality in the AWT component in OpenJDK 6
made it easier for a remote attacker, in conjunction with other
vulnerabilities, to bypass Java sandbox restrictions. (CVE-2012-0547)
