Description Huzaifa S. Sidhpurwala 2012-11-17 11:15:37 UTC
Mozilla security researcher moz_bug_r_a4 reported that if code executed by the evalInSandbox function sets location.href, it can get the wrong subject principal for the URL check, ignoring the sandbox's Javascript context and gaining the context of evalInSandbox object. This can lead to malicious web content being able to perform a cross-site scripting (XSS) attack or stealing a copy of a local file if the user has installed an add-on vulnerable to this attack.
