"It was discovered that Ceph incorrectly handled the handle_command
function. A remote authenticated user could use this issue to cause
Ceph to crash, resulting in a denial of service. (CVE-2016-5009)

Rahul Aggarwal discovered that Ceph incorrectly handled the
authenticated-read ACL. A remote attacker could possibly use this
issue to list bucket contents via a URL. (CVE-2016-7031)

Diluga Salome discovered that Ceph incorrectly handled certain POST
objects with null conditions. A remote attacker could possibly use
this issue to cuase Ceph to crash, resulting in a denial of service.
(CVE-2016-8626)

Yang Liu discovered that Ceph incorrectly handled invalid HTTP Origin
headers. A remote attacker could possibly use this issue to cuase Ceph
to crash, resulting in a denial of service. (CVE-2016-9579).
