Ubuntu Security Notice 1553-1 - It was discovered that the Beans component in OpenJDK 6 did not 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. 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. Various other issues were also addressed.
