potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2011-2982)
A dangling pointer flaw was found in the Firefox Scalable Vector Graphics

containing malicious JavaScript could cause Firefox to execute that
JavaScript with the privileges of the user running Firefox. (CVE-2011-2981)
A flaw was found in the way Firefox handled malformed JavaScript. A web

It was found that a malicious web page could execute arbitrary code with
the privileges of the user running Firefox if the user dropped a tab onto
the malicious web page. (CVE-2011-2984)
