Summary

Mozilla Firefox 3.0.x before 3.0.18, 3.5.x before 3.5.8, and 3.6.x before 3.6.2; Thunderbird before 3.0.2; and SeaMonkey before 2.0.3 allow remote attackers to perform cross-origin keystroke capture, and possibly conduct cross-site scripting (XSS) attacks, by using the addEventListener and setTimeout functions in conjunction with a wrapped object. NOTE: this vulnerability exists because of an incomplete fix for CVE-2007-3736.
