It will take place during the BlackHat/DefCon conference in Las Vegas next week. The awards are both serious and funny, featuring categories such as Best Server-Side Bug, Mass 0wnage, Lamest Vendor Response and of course Best Song! Slashdot readers are invited to submit nominations. What is your favorite security bug?
