Hopefully this will help alleviate the amount of adobe reader exploited vulnerabilties.
The new version of Adobe Reader will feature sandboxing security technology designed to add an additional layer of protection against attacks targeting the popular PDF viewer. Adobe Reader Protected Mode will be enabled by default and included in Adobe Reader browser plug-ins for all the major browsers. The sandbox mechanism will keep PDF processing, such as JavaScript execution, 3D rendering, and image parsing, to a confined area and prevent applications from installing or deleting files, modifying system information, or accessing processes.
Hopefully this will help alleviate the amount of adobe reader exploited vulnerabilties.
