CVE-2014-6418

Published: 28 September 2014

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor.

From the Ubuntu security team

James Eckersall discovered a flaw in how the Ceph filesystem validates auth replies. A remote attacker could exploit this flaw to cause a denial of service (system crash) or possibly have other unspecified impact.
