source: http://www.securityfocus.com/bid/3122/info An issue which affects users of multiple web browsers on Microsoft Windows platforms has been discovered. Multiple malicious IMG tags may cause a denial of services to users who view webpages they are embedded into. Any medium which allows web users to embed a sufficient amount of HTML code that will be displayed to other users(forums, guestbooks, etc.) is a potential attack vehicle for a malicious user. Additionally, malicious webmasters may construct webpages which exploit this vulnerability. The multiple malicious IMG tags will contain a unique 'mailto:' link, forcing the affected browser to open a corresponding number of e-mail compose windows. At the very least the browser will crash, but system resources may be exhausted enough to cause the entire machine to crash. Post 100+ IMG Tags, each with a unique 'mailto:' link. <img src="mailto:email@example.com"> <img src="mailto:firstname.lastname@example.org"> etc.
