    CVE-2014-6417

    net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket.
