Summary: Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat OpenStack 3.0. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: OpenStack 3 - noarch, x86_64 3. Description: 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. This update fixes the following security issues: * A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate cookies. If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash. (CVE-2013-2206, Important) * An invalid free flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to corrupt kernel memory via crafted sendmsg() calls, allowing them to cause a denial of service or, potentially, escalate their privileges on the system. (CVE-2013-2224, Important) * A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers. (CVE-2013-2146, Moderate) * An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate) * Information leak flaws in the Linux kernel's Bluetooth implementation could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2012-6544, Low) * An information leak flaw in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space. (CVE-2013-2237, Low) In addition, the following bugs and features have been addressed: 995409, 995125, 993251, 985838, 975974 More information on the Red Hat Enterprise Linux 6.4 kernel packages upon which these custom kernel packages are based is available in RHSA-2013:1173: https://rhn.redhat.com/errata/RHSA-2013-1173.html All Red Hat OpenStack 3.0 users deploying the OpenStack Networking service are advised to install these updated packages. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 This Red Hat OpenStack 3.0 kernel may be installed by running this command while logged in as the root user on a system that has the required entitlements and subscriptions attached: # yum install "kernel-2.6.*.openstack.el6.x86_64" Documentation for both stable and preview releases of Red Hat OpenStack is available at: https://access.redhat.com/site/documentation/Red_Hat_OpenStack/ In particular it is highly recommended that all users read the Release Notes document for the relevant Red Hat OpenStack release prior to installation. 5. Bugs fixed (http://bugzilla.redhat.com/): 922414 - CVE-2012-6544 Kernel: Bluetooth: HCI & L2CAP information leaks 971309 - CVE-2013-2146 Kernel: perf/x86: offcore_rsp valid mask for SNB/IVB 976562 - CVE-2013-2206 kernel: sctp: duplicate cookie handling NULL pointer dereference 979936 - CVE-2013-2224 kernel: net: IP_REPOPTS invalid free 981220 - CVE-2013-2237 Kernel: net: af_key: initialize satype in key_notify_policy_flush 981552 - CVE-2013-2232 Kernel: ipv6: using ipv4 vs ipv6 structure during routing lookup in sendmsg 6.
