Red Hat Security Advisory 2013-1080-01 - Red Hat OpenStack 3.0 includes a custom Red Hat Enterprise Linux 6.4 kernel. These custom kernel packages include support for network namespaces, this support is required to facilitate advanced OpenStack Networking deployments. A flaw was found in the tcp_read_sock() function in the Linux kernel's IPv4 TCP/IP protocol suite implementation in the way socket buffers were handled. A local, unprivileged user could trigger this issue via a call to splice(), leading to a denial of service.
