CVE-2014-6418: High severity linux kernel vulnerability

Published Sep 16, 2014
·
Updated

A flaw was found in the kernels handling of ceph authentication tickets.

The auth reply could be returned to a client unvalidated.

Other sources

net/ceph/authx.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.
