CVE-2014-8632

Estado: ModificadaMedia (4.3)—

The structured-clone implementation in Mozilla Firefox before 34.0 and SeaMonkey before 2.31 does not properly interact with XrayWrapper property filtering, which allows remote attackers to bypass intended DOM object restrictions by leveraging property availability after XrayWrapper removal.
