Date of Resolved Release
Security Vulnerabilities in the Java Runtime Environment may allow Same Origin Policy to be Bypassed
Security vulnerabilities in the Java Runtime Environment may allow an untrusted applet that is loaded from a remote system to circumvent network access restrictions and establish socket connections to certain services running on machines other than the one that the applet was downloaded from. This may allow the untrusted remote applet the ability to exploit any security vulnerabilities existing in the services it has connected to.
Sun acknowledges with thanks, Gregory Fleischer for bringing these issues to our attention.
2. Contributing Factors
This issue can occur in the following releases for Windows, Solaris, and Linux:

Java(TM) Plug-in 1.5.0_11-b03
The above example indicates the version of the JRE that the browser uses is 1.5.0_11.
There are no predictable symptoms that would indicate that the above issue has been exploited.
