SUMMARY

Macromedia has recently become aware of a vulnerability 
where a hand edited malformed Macromedia Flash movie (SWF) 
header can be exploited to cause a buffer over-write issue 
which could potentially lead to execution of arbitrary code. 

~~~~~~
ISSUES

This can only occur with Macromedia Flash movies (SWF) that 
have been hand edited with a binary editor; Macromedia Flash, 
the authoring tool, will not output movies with this 
vulnerability. 

~~~~~~~~
SOLUTION

Customers should follow the recommendations found in this 
bulletin and download the latest Macromedia Flash Player.

~~~~~~~~~~~~~~~~~~~~~~~~
WHAT MACROMEDIA IS DOING

Macromedia has isolated the issue and released an updated 
player (6,0,65,0 or later) which is available for download 
on the Macromedia Player Download Center:

Flash Player and invests considerable ongoing effort to 
ensure that the security and privacy of all Macromedia

verify and fix this issue.  Both companies are committed 
to security for their customers.
