Adobe has released a critical security update for Adobe Shockwave Player which resolves memory corruption vulnerabilities that could lead to code execution on the Windows and Macintosh operating systems.
Although I have yet to need Shockwave Player on this computer, there are still many people who use it. If you have Shockwave Player installed, please update to the latest version.
The newest version 12.1.9.159 is available here: http://get.adobe.com/shockwave/. As usual, watch for any pre-checked add-ons not needed for the update.
