Description Huzaifa S. Sidhpurwala 2013-10-28 04:26:18 UTC 
Security researcher Jordi Chancel discovered a method to put arbitrary HTML content within <select> elements and place it in arbitrary locations. This can be used to spoof the displayed addressbar, leading to clickjacking and other spoofing attacks.

In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
