Updated Red Hat Enterprise MRG Realtime packages that fix multiple security issues and add one enhancement are now available for Red Hat Enterprise MRG 2.5.

Red Hat Product Security has rated this update as having Moderate 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.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers.

MRG Realtime provides the highest levels of predictability for consistent low-latency response times to meet the needs of time-sensitive workloads. MRG Realtime also provides new levels of determinism by optimizing lengthy kernel code paths to ensure that they do not become bottlenecks. This allows for better prioritization of applications, resulting in consistent, predictable response times for high-priority applications.

  - A flaw was found in the way the Linux kernel's keys     subsystem handled the termination condition in the     associative array garbage collection functionality. A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-3631)

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions. On hosts with an Intel processor and     invept VM exit support, an unprivileged guest user     could use these instructions to crash the     guest.(CVE-2014-3645)

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invvpid     (Invalidate Translations Based on VPID) instructions.
    On hosts with an Intel processor and invppid VM exit     support, an unprivileged guest user could use these     instructions to crash the guest.(CVE-2014-3646)

  - A flaw was found in the way the Linux kernel's KVM     subsystem handled non-canonical addresses when     emulating instructions that change the RIP (for     example, branches or calls). A guest user with access     to an I/O or MMIO region could use this flaw to crash     the guest.(CVE-2014-3647)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled malformed Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3673)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled duplicate Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3687)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled the association's output queue. A remote     attacker could send specially crafted packets that     would cause the system to use an excessive amount of     memory, leading to a denial of service.(CVE-2014-3688)

  - It was found that the Linux kernel's KVM implementation     did not ensure that the host CR4 control register value     remained unchanged across VM entries on the same     virtual CPU. A local, unprivileged user could use this     flaw to cause a denial of service on the     system.(CVE-2014-3690)

  - An out-of-bounds memory access flaw was found in the     Linux kernel's system call auditing implementation. On     a system with existing audit rules defined, a local,     unprivileged user could use this flaw to leak kernel     memory to user space or, potentially, crash the     system.(CVE-2014-3917)

  - A flaw was found in the way Linux kernel's Transparent     Huge Pages (THP) implementation handled non-huge page     migration. A local, unprivileged user could use this     flaw to crash the kernel by migrating transparent     hugepages.(CVE-2014-3940)

  - The capabilities implementation in the Linux kernel     before 3.14.8 does not properly consider that     namespaces are inapplicable to inodes, which allows     local users to bypass intended chmod restrictions by     first creating a user namespace, as demonstrated by     setting the setgid bit on a file with group ownership     of root.(CVE-2014-4014)

  - An information leak flaw was found in the RAM Disks     Memory Copy (rd_mcp) backend driver of the iSCSI Target     subsystem of the Linux kernel. A privileged user could     use this flaw to leak the contents of kernel memory to     an iSCSI initiator remote client.(CVE-2014-4027)
