CVE-2014-6416
Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
