Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
