    Reminds me of openbsd backdoor

    It is obvious that there is range check missing for user sent data.
    This bug is present because developers
    1. inserted security hole intentionally
    2. are retards

    A kernel developer who can submit kernel fix or module shall be good enough to avoid this pre-school level traps/bombs.

    So the only problem is who he is and for whom he is working? Phoronix has an issue tracing back tool?

    It is just slightly better than openbsd that it does not take 10 years to be discovered.

      that's why it is dominating the world.

        ok, but seriously...someone should implement a background garbage collector and some meta-error handling in C and C++. That'd get rid of those 'security holes' instantely.
        C++ also support exceptions

        GCC also can check array access, but not for C
        -fbounds-check
        For front ends that support it, generate additional code to check that indices used to access arrays are within the declared range. This is currently only supported by the Java and Fortran front ends, where this option defaults to true and false respectively.

            Well, I'm glad I'm using debian testing, which is so ancient that it is still on 3.2 kernel..
            Yeah, I bet all of you are jealous of me now..

              Actually doing that is a rather interesting way to do a microkernel and there's this project http://www.mosa-project.org/ and Microsoft Midori doing a managed microkernel in C#. I'll definitely be interested to see if either of those actually goes anywhere.

                Lol... really funny.

                C isn't a bad lang, it's just trap central for bad programming.

                  1: If you're on Debian Wheezy or Ubuntu 12.04, you're still affected.
                  The commit introducing this is actually from just before 3.2.
                  2: The patch was committed by a Red Hat employee, but was written by a Parallels employee.
                  Code:

                  Now I'm off to build a new kernel for my Squeeze system.

                    A CIA agent for sure. Linus should really investigate kernel contributors before letting them submit code, because who knows how many CIA agents and/or M$ employees are willing to introduce backdoors in Linux ?

                      Apparently, with SELinux enabled on Fedora 18, the exploit code failed to run.
