Summary

Mozilla Firefox before 1.8.0.13 and 1.8.1.x before 1.8.1.5 does not perform a security zone check when processing a wyciwyg URI, which allows remote attackers to obtain sensitive information, poison the browser cache, and possibly enable further attack vectors via (1) HTTP 302 redirect controls, (2) XMLHttpRequest, or (3) view-source URIs.
