Security Model

  • Closer to complete security model
  • Still some specific areas outstanding (TLS, addons esp. addon SDK notably)
  • publish to wiki and integrate with existing content

Maintaining a secure sandbox

  • point of a approval for landing?
  • sandbox changes
  • architectural changes which impact sandbox (e.g. changes to remoted APIs which move security boundaries)

Next Steps

  • continue auditing the code to determine if gecko parts conform to security model
    • First pass of IPDL audit, complete message manager audit
  • engage additional resources to get chromium fuzzer work started
  • fuzzing is working on fuzzer for message manager (aim to complete this month)
  • get the security model up onto the wiki
