Description Huzaifa S. Sidhpurwala 2012-07-14 07:53:07 EDT
Mozilla security researcher moz_bug_r_a4 reported a cross-site scripting (XSS) attack through the context menu using a data: URL. In this issue, context menu functionality ("View Image", "Show only this frame", and "View background image") are disallowed in a javascript: URL but allowed in a data: URL, allowing for XSS. This can lead to arbitrary code execution. 

Comment 1 Huzaifa S. Sidhpurwala 2012-07-14 07:56:18 EDT

Red Hat would like to thank the Mozilla project for reporting this issue.  Upstream acknowledges moz_bug_r_a4 as the original reporter of this issue.
