Defeating XP SP2 Heap Protection

hobo2k writes "XP SP2 included canary values and hardware-implemented execution protection in order to avoid exploitable buffer overruns. Now Positive Technologies has released an article describing one way that protection could be bypassed. To solve the problem, they provide a program which disables the small allocation heap as described here. CNET reports that SP2 has been foiled."

      No. Linux is like masturbation. And BSD is like necrophilia.

      Yeah, so sorry about the AIDS you already contracted.

      Remember: the only safe computing is NO COMPUTING. If you feel like you have to use a computer, then staying off-line is the only sure way to stay disease-free. There's nothing shameful about it; you'll not go blind.

      Now, since I know you kids are going to want to play your Counter Strike anyway, it's best to make sure you only game with people you already know and trust. Don't deathmatch with that hussy you found at the airport bar, and never accept files from strangers. You don't know who else they've swapped files with.

    I'm shocked! I have been reading all these independent studies, and according to Forrester, Windows users have fewer vulnerabilities. Check it out yourself, if you don't believe!
    http://www.microsoft.com/windowsserversy stem/facts /analyses/default.mspx#EHAA

    It's a fact. So this vulnerability, and the dozen others I've been patching at the work, are just some kind of imagination. Or maybe Linux / BSD / OS X users have just amazing amounts of vulnerabilities (counted together, OS & apps).

    I'm drunk. And it's not a surprise. Every hardcore Linux geek (like myself), who has to maintain Windows networks for living, have more drinking problems than those who are using solely operating systems and software which are free as speech (as opposed to beer).

    Responsible for security of Windows network? Next recommendation for security enhancements: different operating systems, no more IE. If there are costs, then they're definitely worth it. Microsoft has proved that they don't care. All they care is money, monopoly and marketing (FUD / brainwashing / propaganda).

    Yeah, it's kind of silly for them to focus on a problem with software DEP instead of hardware DEP.

    I mean, hardware DEP is available on <1% of the installed base - and the base is growing! Within 5 years this won't be an issue at all.

    Well, unless you're using hardware that >5 years old at that time. But that's crazy talk - I mean, everyone replaces their system every 6 months.
