Business Impact:

Browser vulnerabilities are a prime target for the criminal underground as they are simple to exploit if you can entice a user to click a link.  Malware botnets are infamous for taking advantage of browser vulnerabilities to infect systems and secretly install programs that steal passwords or other sensitive information or simply use the system as a spam bot for profit or to infect new systems.

Technical Description
