-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Sun Java Runtime. User interaction is
required in that a target must visit a malicious page.

forge their own and force the removal of sandbox restrictions.
Successful exploitation leads to code execution under the context of the
user running the browser.
