> flaw But, but: how is it even possible for a user-mode application to break the OS security? It must be due to a flaw in the OS, right?

  If you consider the ability to install code as root as a flaw in the OS, which is the security model of some platforms such as iOS.

    Installing code as root does not necessarily mean granting root privileges to said code. (Even running an application under the root account shouldn't require or imply that. For example, if I use a text editor as root, I still do not want it to be able to reformat the hard drive.)

      The code doing the installation as root does have root privileges.
