Whats the payload?
Depends, but the vulnerability can allow attackers to take complete control of the machine so the potential for mayhem is high. Most attacks so far are recruiting PCs into botnets, presumably to be used for other attacks or malware propagation at a later date. They’re also depositing a stunning amount of adware on victimized machines, as Sunbelt researcher Adam Thomas described in a blog posting. The potential for trouble, rather than the current infection rate, is why organizations such as Secunia are concerned at the moment.
