Java plugin vulnerability?

["Lee Whatley, Contractor" <lwhatley navo hpc mil>]

Hello all,

Does anyone know if the java browser plugin that is included in the RHEL 
3 extras channel is vulnerable to this:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1029

The advisory only mentions SUN java and I seem to recall that the RHEL 
package is based on IBM java, but I don't know if they are based off of 
the same code or what.

Thanks in advance,
-Lee
