Remotely Crash OpenBSD

Posted by CowboyNeal on from the even-the-best-of-us dept.

*no comment* writes "If you are running OpenBSD on your IPv6 install, it might be time to upgrade to -current. (just kidding) There is, however, a way to crash OpenBSD 3.4 with a couple of simple IPv6 commands. Georgi Guninski, found the problem. To quote Theo, 'it is just a crash.'" It is unknown if the bug could be used to execute arbitrary code, but it does require patching a Linux kernel (or rolling your own network stack) to exploit.

  1. patching a Linux kernel? by DaHat · · Score: 0, Redundant

    Why would you patch a Linux kernal for a BSD problem? That's like patching Windows due to a linux problem.

    ..or should this read "If you are running IPv6 on your OpenBSD install.."

  4. do FreeBSD & OpenBSD use the same kernel? by xot · · Score: 0, Redundant

    Pardon my ignorance..but do FreeBSD n Open BSD use the same kernel?If they do does that mean that this bug would affect FreeBSD as well?

    How do you know its not sarcasm?

    To me it sounds just that. Although I agree that there are instances of anti-MS bias, this is not one.

    Besides, the reason MS gets made fun of is only because there's always "just a crash" - the reason OpenBSD doesn't get made fun of is because its so rare that it ever happens.

  7. "just a crash"?!! by CAIMLAS · · Score: 0, Redundant

    Yeah fucking right!

    No, it's not "just a crash", it's a "very easily executed DOS" that could be perpetuated indefinately if the person on the receving end wasn't aware of this exploit.

    Theo: don't be so egotistical and elitist. Such attitudes lead to failure and defeat. History teaches us this.
