Ubuntu Security Notice 5880-1 - Christian Holler discovered that Firefox did not properly manage memory when using PKCS 12 Safe Bag attributes. An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes. Johan Carlsson discovered that Firefox did not properly manage child iframe's unredacted URI when using Content-Security-Policy-Report-Only header. An attacker could potentially exploits this to obtain sensitive information.
