Description Huzaifa S. Sidhpurwala 2012-10-11 03:45:36 UTC

Mozilla security researcher moz_bug_r_a4 reported a regression where security wrappers are unwrapped without doing a security check in defaultValue(). This can allow for improper access access to the Location object and the potential for arbitrary code execution.
