Mandriva Linux Security Advisory 2012-167 - Mozilla security researcher moz_bug_r_a4 reported a regression where security wrappers are unwrapped without doing a security check in defaultValue().

The mozilla firefox packages has been upgraded to the latest version which is unaffected by this security flaw.
