Ubuntu: Security update for OpenJDK

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.

Updated packages are available from security.ubuntu.com.
