Cross-site JavaScript injection using event handlers shutdown reported a method of injecting running JavaScript code into a page on another site using a modal alert to suspend an event handler while a new page is being loaded. This vulnerability allows an attacker to steal any confidential information the new page might contain, including any passwords and cookies which might allow the attacker to log on to that site as the victim. shutdown also reported a variant using the two-argument form of eval() that did not require a modal dialog and would be much less obtrusive. moz_bug_r_a4 reported two variants that bypassed our initial fixes, one using "new Script()", the other extending the eval() attack using window.__proto__ Note: Thunderbird shares the JavaScript engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until you can upgrade to a fixed version.

Lifting embargo
I notice that this bug, and many of the others for RHSA-2006:0329-01 <http://rhn.redhat.com/errata/RHSA-2006-0329.html> have RELEASE_PENDING status; but since that RHSA has been issued, shouldn't these bugs be CLOSED ERRATA now?
An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
