Adobe Flash Player Now Sandboxed in Safari on OS X Mavericks
Flash is a common target for malware and a number of attacks affecting Mac users. Adobe announced that it's Flash Player will now be sandboxed for it's Safari version found on OSX Mavericks. Preventing malware targeting Flash from accessing sensitive data and system resources. Apple describes sandboxing as providing a last line of defense against the theft, corruption, or deletion of user data.
For the technically people out their, this means that there is a specific com.macromedia.Flash Player.plugin.sb file defining the security permissions for Flash Player when it runs within the sandboxed plugin process. As you might expect, Flash Player’s capabilities to read and write files will be limited to only those locations it needs to function properly. The sandbox also limits Flash Player’s local connections to device resources and inter-process communication (IPC) channels. Finally, the sandbox limits Flash Player’s networking privileges to prevent unnecessary connection capabilities.
