Detail
| Problem Description: Updated kernel-rt packages that fix multiple security issues and one bug are now available for Red Hat Enterprise MRG 2.5. Red Hat Product Security 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: MRG Realtime for RHEL 6 Server v.2 - noarch, x86_64 3. Description: The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. * A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important) * Multiple use-after-free flaws and an integer overflow flaw were found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use either of these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654, CVE-2014-4655, CVE-2014-4656, Moderate) * An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low) This update also fixes the following bug: * Prior to this update, the netconsole module was unavailable on MRG Realtime kernels due to locking issues that disabled it. These locking issues have been corrected, allowing the netconsole module to be re-enabled and functional on Realtime kernels. (BZ#1088923) Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.45 and correct these issues. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5. Bugs fixed (https://bugzilla.redhat.com/): 1113406 - CVE-2014-4652 Kernel: ALSA: control: protect user controls against races & memory disclosure 1113409 - CVE-2014-4653 Kernel: ALSA: control: do not access controls outside of protected regions 1113445 - CVE-2014-4654 CVE-2014-4655 Kernel: ALSA: control: use-after-free in replacing user controls 1113470 - CVE-2014-4656 Kernel: ALSA: control: integer overflow in id.index & id.numid 1122982 - CVE-2014-5077 Kernel: net: SCTP: fix a NULL pointer dereference during INIT collisions |

| Title: | RHSA-2014:1392: kernel security, bug fix, and enhancement update (Important) | ||
| Description: | The kernel packages contain the Linux kernel, the core of any Linux operating system. * A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important) * An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file (/dev/fb*) could possibly use this flaw to escalate their privileges on the system. (CVE-2013-2596, Important) * A flaw was found in the way the ipc_rcu_putref() function in the Linux kernel's IPC implementation handled reference counter decrementing. A local, unprivileged user could use this flaw to trigger an Out of Memory (OOM) condition and, potentially, crash the system. (CVE-2013-4483, Moderate) * It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate) * It was found that the try_to_unmap_cluster() function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUG_ON() macro in the mlock_vma_page() function. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-3122, Moderate) * A flaw was found in the way the Linux kernel's kvm_iommu_map_pages() function handled IOMMU mapping failures. A privileged user in a guest with an assigned host device could use this flaw to crash the host. (CVE-2014-3601, Moderate) * Multiple use-after-free flaws were found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use either of these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654, CVE-2014-4655, Moderate) * A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in a system crash or privilege escalation. (CVE-2014-5045, Moderate) * An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel's LZO implementation processed Literal Runs. A local attacker could, in extremely rare cases, use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-4608, Low) Red Hat would like to thank Vladimir Davydov of Parallels for reporting CVE-2013-4483, Jack Morgenstein of Mellanox for reporting CVE-2014-3601, Vasily Averin of Parallels for reporting CVE-2014-5045, and Don A. Bailey from Lab Mouse Security for reporting CVE-2014-4608. The security impact of the CVE-2014-3601 issue was discovered by Michael Tsirkin of Red Hat. This update also fixes several hundred bugs and adds numerous enhancements. Refer to the Red Hat Enterprise Linux 6.6 Release Notes for information on the most significant of these changes, and the Technical Notes for further information, both linked to in the References. All Red Hat Enterprise Linux 6 users are advised to install these updated packages, which correct these issues, and fix the bugs and add the enhancements noted in the Red Hat Enterprise Linux 6.6 Release Notes and Technical Notes. The system must be rebooted for this update to take effect. | ||

| Title: | RHSA-2014:1724 -- kernel security and bug fix update (Important) | ||
| Description: | The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. (CVE-2014-3611, Important) * A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important) * 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) and invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invept/invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. (CVE-2014-3645, CVE-2014-3646, Moderate) * A use-after-free flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system. (CVE-2014-4653, Moderate) Red Hat would like to thank Lars Bull of Google for reporting CVE-2014-3611, and the Advanced Threat Research team at Intel Security for reporting CVE-2014-3645 and CVE-2014-3646. Bug fixes: * A known issue that could prevent Chelsio adapters using the cxgb4 driver from being initialized on IBM POWER8 systems has been fixed. These adapters can now be used on IBM POWER8 systems as expected. (BZ#1130548) * When bringing a hot-added CPU online, the kernel did not initialize a CPU mask properly, which could result in a kernel panic. This update corrects the bug by ensuring that the CPU mask is properly initialized and the correct NUMA node selected. (BZ#1134715) * The kernel could fail to bring a CPU online if the hardware supported both, the acpi-cpufreq and intel_pstate modules. This update ensures that the acpi-cpufreq module is not loaded in the intel_pstate module is loaded. (BZ#1134716) * Due to a bug in the time accounting of the kernel scheduler, a divide error could occur when hot adding a CPU. To fix this problem, the kernel scheduler time accounting has been reworked. (BZ#1134717) * The kernel did not handle exceptions caused by an invalid floating point control (FPC) register, resulting in a kernel oops. This problem has been fixed by placing the label to handle these exceptions to the correct place in the code. (BZ#1138733) * A previous change to the kernel for the PowerPC architecture changed implementation of the compat_sys_sendfile() function. Consequently, the 64-bit sendfile() system call stopped working for files larger than 2 GB on PowerPC. This update restores previous behavior of sendfile() on PowerPC, and it again process files bigger than 2 GB as expected. (BZ#1139126) * Previously, the kernel scheduler could schedule a CPU topology update even though the topology did not change. This could negatively affect the CPU load balancing, cause degradation of the system performance, and eventually result in a kernel oops. This problem has been fixed by skipping the CPU topology update if the topology has not actually changed. (BZ#1140300) * Previously, recovery of a double-degraded RAID6 array could, under certain circumstances, result in data corruption. This could happen because the md driver was using an optimization that is safe to use only for single-degraded arrays. This update ensures that this optimization is skipped during the recovery of double-degraded RAID6 arrays. (BZ#1143850) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. | ||
