Description Huzaifa S. Sidhpurwala 2012-08-27 04:53:44 UTC 
Mozilla security researcher moz_bug_r_a4 reported that certain security checks in the location object can be bypassed if chrome code is called content in a specific manner. This allowed for the loading of restricted content. This can be combined with other issues to become potentially exploitable.
