Dear John Smith, Actually, browser DoS may be quite serious vulnerability, depending on nature of DoS. Think about e.g. banner or content exchange network, social networks, web boards, etc where browser vulnerability may be used against site or page because it will harm any visitors of this site or page. In case of this very vulnerability, most serious impact may be from e-mail vector. --Friday, May 28, 2010, 7:07:50 PM, you wrote to mustlive@xxxxxxxxxxxxxxxxxx: JS> Just a few cents - DoS in webbrowsers doesn't fall under the category of JS> "vulnerabilities" rather more of "annoyances".
