- --------------------------BEGIN INCLUDED TEXT--------------------

OVERVIEW:

        A vulnerability has been patched in various F-Secure products, 
        exploitation of which may result in the execution of arbitrary code.


IMPACT:

       F-Secure have provided the following information regarding this
       vulnerability:

       "If attackers send specially-made compressed file archives to users, 
       whose antivirus software is set to scan inside compressed archives, 
       this causes an integer overflow. The result is a controlled buffer 
       overflow attack. It allows the attackers to control the computer on 
       the system level." [1]


MITIGATION:

       Patches have been released correcting this vulnerability. Some 
       products will be updated automatically, but others will require 
       manual application of the patch. For more information, please see the
