    Microsoft buggy as ever

    Wrote a command line fuzzer (originally forfuzzing *nix setuid binaries),
    running it on windows gave astonishing results almost every third
    commandline application crashed for example expand.exe,extrac32.exe,fontview.exe,evetvwr.exe.
    (only one of them poses a real threat can you guess ?)
    I wonder what microsoft is upto.

    The fuzzer is at

    Ok then

    Explain it to me

    sounds like the "fuzzer" is not letting go of a process...

    "Crashed"

    What crashed? the os? the program?

    Hi

    "Fuzzing" or "Fuzz testing" is one among several software testing methods,
    for an example see Soda's Tutorial[1]. Looks like warl0ck7 used
    a "fuzzer" of his own making to test various programs (console applications,
    hence "command line"). As an effect, quite a few of them crashed.
    He argues that this implies bad software development, and might
    allow for possible privilege escalation.

    Software testing itself is a process used to help identify the correctness,
    completeness and quality of developed computer software[2]. With that in
    mind, testing can never completely establish the correctness of computer
    software. Only the process of formal verification can prove that there are no
    defects.

    Reminds me of physics We are building theoretical models and
    theories and test them via verification by experiment. However,
    even if all experiments we can think of agree with the predictions,
    we never can be sure to have the correct theory.

    Cheers

    to sensitive to be listed here).

    C:\>clfuzz.py extrac32 STR
