02:57:13 - eXpl0it3r: Crashes in some ASM code
02:57:47 - eXpl0it3r: Pretty sure it's a stack overflow though
02:58:15 - eXpl0it3r: Which is theoretically quite serious
02:58:52 - eXpl0it3r: And since all it needs is a spoofed DNS entry to make it crash...
03:00:37 - eXpl0it3r: Then again this might actually be a Qt4 bug
