CVE-2011-2981

First published: Thu Aug 18 2011(Updated: )

The event-management implementation in Mozilla Firefox before 3.6.20, SeaMonkey 2.x, Thunderbird 3.x before 3.1.12, and possibly other products does not properly select the context for script to run in, which allows remote attackers to bypass the Same Origin Policy or execute arbitrary JavaScript code with chrome privileges via a crafted web site.
