    Might be of some interest to any sys admins who frequent this board.

    Proof of Concept code has been released for CVE-2014-0196. Credit to Matt Daley: http://bugfuzz.com/stuff/cve-2014-0196-md.c

    Thanks Matt. Thanks for making me try it on all the servers I manage to check if Im vulnerable. Like I had nothing else to do on this sunny Friday. :p

    Seriously though, one machine was vulnerable. I rather know about this stuff then not know about it. Im sure others here are the same.

    Did you get root on the box in question? Just compile that c file and run it?

    To compile, run:
    cc -o a.out -lpthread -lopenpty cve-2014-0196-md.c
