Updated kernel-rt packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.5.

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.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.

  * A denial of service flaw was found in the way the Linux     kernel's IPv6 implementation processed IPv6 router     advertisement (RA) packets. An attacker able to send a     large number of RA packets to a target system could     potentially use this flaw to crash the target system.
    (CVE-2014-2309, Important)

  * A flaw was found in the way the Linux kernel's netfilter     connection tracking implementation for Datagram     Congestion Control Protocol (DCCP) packets used the     skb_header_pointer() function. A remote attacker could     use this flaw to send a specially crafted DCCP packet     to crash the system or, potentially, escalate their     privileges on the system. (CVE-2014-2523, Important)

  * A flaw was found in the way the Linux kernel's CIFS     implementation handled uncached write operations with     specially crafted iovec structures. An unprivileged     local user with access to a CIFS share could use this     flaw to crash the system, leak kernel memory, or,     potentially, escalate their privileges on the system.
    (CVE-2014-0069, Moderate)

  * A flaw was found in the way the Linux kernel handled     pending Floating Pointer Unit (FPU) exceptions during     the switching of tasks. A local attacker could use this     flaw to terminate arbitrary processes on the system,     causing a denial of service, or, potentially, escalate     their privileges on the system. Note that this flaw only     affected systems using AMD CPUs on both 32-bit and     64-bit architectures. (CVE-2014-1438, Moderate)

  * It was found that certain protocol handlers in the Linux     kernel's networking implementation could set the     addr_len value without initializing the associated data     structure. A local, unprivileged user could use this     flaw to leak kernel stack memory to user space using the     recvmsg, recvfrom, and recvmmsg system calls.
    (CVE-2013-7263, CVE-2013-7265, Low)

  * An information leak flaw was found in the Linux kernel's     netfilter connection tracking IRC NAT helper     implementation that could allow a remote attacker to     disclose portions of kernel stack memory during IRC     DCC (Direct Client-to-Client) communication over NAT.
    (CVE-2014-1690, Low)

  * A denial of service flaw was discovered in the way the     Linux kernel's SELinux implementation handled files with     an empty SELinux security context. A local user who has     the CAP_MAC_ADMIN capability could use this flaw to     crash the system. (CVE-2014-1874, Low)

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3034 advisory.

  - The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between     locked instructions and write-combined memory types, which allows local users to cause a denial of service     (system hang) via a crafted application, aka the errata 793 issue. (CVE-2013-6885)

  - The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly     manage tty driver access in the LECHO & !OPOST case, which allows local users to cause a denial of     service (memory corruption and system crash) or gain privileges by triggering a race condition involving     read and write operations with long strings. (CVE-2014-0196)

  - The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count     the addition of routes, which allows remote attackers to cause a denial of service (memory consumption)     via a flood of ICMPv6 Router Advertisement packets. (CVE-2014-2309)

  - Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before     3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers     an invalid memory copy affecting certain cancel_work_item data. (CVE-2014-0049)

  - The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer     parameter. (CVE-2014-0038)

  - Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in     the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value.
    (CVE-2013-4587)

  - The mISDN_sock_recvmsg function in drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does not     ensure that a certain length value is consistent with the size of an associated data structure, which     allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or     (3) recvmsg system call. (CVE-2013-7266)
