Description:   A vulnerability was reported in Java Runtime Environment (JRE) in the processing of fonts. A remote user can access files on the target user's system. A remote user can cause arbitrary applications on the target user's system to be executed.

A remote user can create a specially crafted applet or application that, when loaded by the target user, will trigger a buffer overflow in the processing of fonts to gain access to files on the target system or execute arbitrary applications residing on the target system.

John Heasman of NGSSoftware reported this vulnerability.

Impact:   A remote user can create an applet or application that, when loaded by the target user, will access files or execute arbitrary applications on the target user's system.
Solution:   Sun has issued the following fixes.

* JDK and JRE 5.0 Update 10 or later
* SDK and JRE 1.4.2_18 or later
