Description:   Several vulnerabilities were reported in Sun's Java Runtime Environment (JRE). A remote applet may be able to gain elevated privileges.

Three vulnerabilities exist in certain "reflection" APIs in JRE. A remote, untrusted applet may be able to gain elevated privleges. For example, an applet may be able to obtain permissions to read and write local files or execute local applications with the privileges of the user running the untrusted applet.

Sun credits Adam Gowdiak with reporting these vulnerabilities.

Impact:   A remote applet may be able to gain elevated privileges, such as the ability to read or write to files on the target system or execute applications on the target system with the privileges of the user running the applet.
Solution:   The vendor has issued a fix:

* SDK and JRE 1.4.2_09 and later
* JDK and JRE 5.0 Update 4 and later
