    It’s an easy way to modify the binary to load extra code, which can alter how it behaves.
    • hvdijk 5y ago
      Sure, but only if you have write access to the binary. If you have that you can already replace it with anything you like, so I am not seeing the privilege escalation there.

        Consider the context in which PT_INTERP is loaded and executed.
        • hvdijk 5y ago
          There should be no situation where a malformed or unexpected PT_INTERP leads to privilege escalation. If you believe you have found such a situation, please report it.
