Description Huzaifa S. Sidhpurwala 2012-10-10 23:45:36 EDT
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. 

External Reference:



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