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.

Red Hat Security Advisory 2013-1034-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Information leaks in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization security feature.

Red Hat Security Advisory 2013-0829-01 - Security fixes: It was found that the kernel-rt update RHBA-2012:0044 introduced an integer conversion issue in the Linux kernel's Performance Events implementation. This led to a user-supplied index into the perf_swevent_enabled array not being validated properly, resulting in out-of-bounds kernel memory access. A local, unprivileged user could use this flaw to escalate their privileges. A public exploit for CVE-2013-2094 that affects Red Hat Enterprise MRG 2 is available. Refer to Red Hat Knowledge Solution 373743, linked to in the References, for further information and mitigation instructions for users who are unable to immediately apply this update.
