Over the years Adobe’s software has been regarded as pretty insecure, therefore it is quite refreshing to hear that they are planning to change this with their next major version of Adobe Reader.
From what we can see Adobe Reader 10 and all plugin code will include a sandbox architecture called “Protected Mode”, this should defend systems against vulnerability exploits in Reader.
In recent times Google Chrome has won awards for being extremely secure thanks to using sandbox technologies, therefore even if Adobe Reader 10 vulnerabilities are found they are severely limited thanks to the sandbox.
Full details are understandably scarce at present, however from what we can see Protected Mode will be turned on by default in Reader, this will stop any vulnerabilities from writing to the file system or registry.
