  - A race condition was found in the Linux kernel, present     since v3.14-rc1 through v4.12. The race happens between     threads of inotify_handle_event() and vfs_rename()     while running the rename operation against the same     file. As a result of the race the next slab data or the     slab's free list pointer can be corrupted with     attacker-controlled data, which may lead to the     privilege escalation.(CVE-2017-7533i1/4%0

  - A privilege-escalation vulnerability was discovered in     the Linux kernel built with User Namespace     (CONFIG_USER_NS) support. The flaw occurred when the     ptrace() system call was used on a root-owned process     to enter a user namespace. A privileged namespace user     could exploit this flaw to potentially escalate their     privileges on the system, outside the original     namespace.(CVE-2015-8709i1/4%0

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805i1/4%0

  - 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-2014-3601i1/4%0

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193i1/4%0

  - Race condition in the ion_ioctl function in     drivers/staging/android/ion/ion.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) by calling     ION_IOC_FREE on two CPUs at the same     time.(CVE-2016-9120i1/4%0

  - drivers/hid/hid-picolcd_core.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_PICOLCD is enabled, allows     physically proximate attackers to cause a denial of     service (NULL pointer dereference and OOPS) via a     crafted device.(CVE-2013-2899i1/4%0

  - A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.When     unmounting the underlying device, the system is unable     to free an inode and this will consume resources.
    Repeating this for all available inodes and memory will     create a denial of service situation.(CVE-2015-8953i1/4%0

  - Buffer overflow in the mp_override_legacy_irq()     function in arch/x86/kernel/acpi/boot.c in the Linux     kernel through 4.12.2 allows local users to gain     privileges via a crafted ACPI table.(CVE-2017-11473i1/4%0

  - CVE-2014-7826: kernel/trace/trace_syscalls.c in the     Linux kernel through 3.17.2 did not properly handle     private syscall numbers during use of the ftrace     subsystem, which allowed local users to gain privileges     or cause a denial of service (invalid pointer     dereference) via a crafted application (bnc#904013).

  - CVE-2014-7841: The sctp_process_param function in     net/sctp/sm_make_chunk.c in the SCTP implementation in     the Linux kernel before 3.17.4, when ASCONF is used,     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) via a     malformed INIT chunk (bnc#905100).

  - CVE-2014-7842: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 3.17.4 allowed guest OS users to     cause a denial of service (guest OS crash) via a crafted     application that performs an MMIO transaction or a PIO     transaction to trigger a guest userspace emulation error     report, a similar issue to CVE-2010-5313 (bnc#905312).

  - CVE-2014-8134: The paravirt_ops_setup function in     arch/x86/kernel/kvm.c in the Linux kernel through 3.18     uses an improper paravirt_enabled setting for KVM guest     kernels, which made it easier for guest OS users to     bypass the ASLR protection mechanism via a crafted     application that reads a 16-bit value (bnc#909078).

  - CVE-2014-8369: The kvm_iommu_map_pages function in     virt/kvm/iommu.c in the Linux kernel through 3.17.2     miscalculates the number of pages during the handling of     a mapping failure, which allowed guest OS users to cause     a denial of service (host OS page unpinning) or possibly     have unspecified other impact by leveraging guest OS     privileges. NOTE: this vulnerability exists because of     an incorrect fix for CVE-2014-3601 (bnc#902675).

  - CVE-2014-8559: The d_walk function in fs/dcache.c in the     Linux kernel through 3.17.2 did not properly maintain     the semantics of rename_lock, which allowed local users     to cause a denial of service (deadlock and system hang)     via a crafted application (bnc#903640).

  - CVE-2014-8709: The ieee80211_fragment function in     net/mac80211/tx.c in the Linux kernel before 3.13.5 did     not properly maintain a certain tail pointer, which     allowed remote attackers to obtain sensitive cleartext     information by reading packets (bnc#904700).

  - CVE-2014-9584: The parse_rock_ridge_inode_internal     function in fs/isofs/rock.c in the Linux kernel before     3.18.2 did not validate a length value in the Extensions     Reference (ER) System Use Field, which allowed local     users to obtain sensitive information from kernel memory     via a crafted iso9660 image (bnc#912654).

  - CVE-2014-9585: The vdso_addr function in     arch/x86/vdso/vma.c in the Linux kernel through 3.18.2     did not properly choose memory locations for the vDSO     area, which made it easier for local users to bypass the     ASLR protection mechanism by guessing a location at the     end of a PMD (bnc#912705).

  - uek-rpm: ol7: update update-el to 7.1 (Guangyu Sun)     [Orabug: 20524579]

- It was found that the Linux kernel's Infiniband     subsystem did not properly sanitize input parameters     while registering memory regions from user space via the     (u)verbs API. A local user with access to a     /dev/infiniband/uverbsX device could use this flaw to     crash the system or, potentially, escalate their     privileges on the system. (CVE-2014-8159, Important)

  - A flaw was found in the way the Linux kernel's splice()     system call validated its parameters. On certain file     systems, a local, unprivileged user could use this flaw     to write past the maximum file size, and thus crash the     system. (CVE-2014-7822, Moderate)

  - A flaw was found in the way the Linux kernel's netfilter     subsystem handled generic protocol tracking. As     demonstrated in the Stream Control Transmission Protocol     (SCTP) case, a remote attacker could use this flaw to     bypass intended iptables rule restrictions when the     associated connection tracking module was not loaded on     the system. (CVE-2014-8160, Moderate)

  - It was found that the fix for CVE-2014-3601 was     incomplete: the Linux kernel's kvm_iommu_map_pages()     function still handled IOMMU mapping failures     incorrectly. A privileged user in a guest with an     assigned host device could use this flaw to crash the     host. (CVE-2014-8369, Moderate)

Bug fixes :

  - The maximum amount of entries in the IPv6 route table     (net.ipv6.route.max_size) was 4096, and every route     towards this maximum size limit was counted.
    Communication to more systems was impossible when the     limit was exceeded. Now, only cached routes are counted,     which guarantees that the kernel does not run out of     memory, but the user can now install as many routes as     the memory allows until the kernel indicates it can no     longer handle the amount of memory and returns an error     message.

In addition, the default 'net.ipv6.route.max_size' value has been increased to 16384 for performance improvement reasons.

  - When the user attempted to scan for an FCOE-served     Logical Unit Number (LUN), after an initial LUN scan, a     kernel panic occurred in bnx2fc_init_task. System     scanning for LUNs is now stable after LUNs have been     added.

  - Under certain conditions, such as when attempting to     scan the network for LUNs, a race condition in the     bnx2fc driver could trigger a kernel panic in     bnx2fc_init_task. A patch fixing a locking issue that     caused the race condition has been applied, and scanning     the network for LUNs no longer leads to a kernel panic.

  - Previously, it was not possible to boot the kernel on     Xen hypervisor in PVHVM mode if more than 32 vCPUs were     specified in the guest configuration. Support for more     than 32 vCPUs has been added, and the kernel now boots     successfully in the described situation.

  - When the NVMe driver allocated a namespace queue, it     indicated that it was a request-based driver when it was     actually a block I/O-based driver. Consequently, when     NVMe driver was loaded along with a request-based dm     device, the system could terminate unexpectedly or     become unresponsive when attempting to access data. The     NVMe driver no longer sets the QUEUE_FLAG_STACKABLE bit     when allocating a namespace queue and device- mapper no     longer perceives NVMe driver as request-based; system     hangs or crashes no longer occur.

  - If a user attempted to apply an NVRAM firmware update     when running the tg3 module provided with Scientific     Linux 6.6 kernels, the update could fail. As a     consequence, the Network Interface Card (NIC) could stay     in an unusable state and this could prevent the entire     system from booting. The tg3 module has been updated to     correctly apply firmware updates.

  - Support for key sizes of 256 and 192 bits has been added     to AES-NI.

The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to fix various bugs and security issues.

The following security bugs have been fixed :

    (bnc#853040, bnc#857643). (CVE-2013-7263)

  - Multiple stack-based buffer overflows in the     magicmouse_raw_event function in     drivers/hid/hid-magicmouse.c in the Magic Mouse HID     driver in the Linux kernel through 3.16.3 allowed     physically proximate attackers to cause a denial of     service (system crash) or possibly execute arbitrary     code via a crafted device that provides a large amount     of (1) EHCI or (2) XHCI data associated with an event.
    (bnc#896382). (CVE-2014-3181)

  - The report_fixup functions in the HID subsystem in the     Linux kernel before 3.16.2 allowed physically proximate     attackers to cause a denial of service (out-of-bounds     write) via a crafted device that provides a small report     descriptor, related to (1) drivers/hid/hid-cherry.c, (2)     drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4)     drivers/hid/hid-monterey.c, (5)     drivers/hid/hid-petalynx.c, and (6)     drivers/hid/hid-sunplus.c. (bnc#896390). (CVE-2014-3184)

  - Multiple buffer overflows in the     command_port_read_callback function in     drivers/usb/serial/whiteheat.c in the Whiteheat USB     Serial Driver in the Linux kernel before 3.16.2 allowed     physically proximate attackers to execute arbitrary code     or cause a denial of service (memory corruption and     system crash) via a crafted device that provides a large     amount of (1) EHCI or (2) XHCI data associated with a     bulk response. (bnc#896391). (CVE-2014-3185)

  - Buffer overflow in the picolcd_raw_event function in     devices/hid/hid-picolcd_core.c in the PicoLCD HID device     driver in the Linux kernel through 3.16.3, as used in     Android on Nexus 7 devices, allowed physically proximate     attackers to cause a denial of service (system crash) or     possibly execute arbitrary code via a crafted device     that sends a large report. (bnc#896392). (CVE-2014-3186)

  - The kvm_iommu_map_pages function in virt/kvm/iommu.c in     the Linux kernel through 3.16.1 miscalculated the number     of pages during the handling of a mapping failure, which     allowed guest OS users to (1) cause a denial of service     (host OS memory corruption) or possibly have unspecified     other impact by triggering a large gfn value or (2)     cause a denial of service (host OS memory consumption)     by triggering a small gfn value that leads to     permanently pinned pages. (bnc#892782). (CVE-2014-3601)

  - The WRMSR processing functionality in the KVM subsystem     in the Linux kernel through 3.17.2 did not properly     handle the writing of a non-canonical address to a     model-specific register, which allowed guest OS users to     cause a denial of service (host OS crash) by leveraging     guest OS privileges, related to the wrmsr_interception     function in arch/x86/kvm/svm.c and the handle_wrmsr     function in arch/x86/kvm/vmx.c. (bnc#899192).
    (CVE-2014-3610)

  - arch/x86/kvm/vmx.c in the KVM subsystem in the Linux     kernel through 3.17.2 did not have an exit handler for     the INVVPID instruction, which allowed guest OS users to     cause a denial of service (guest OS crash) via a crafted     application. (bnc#899192). (CVE-2014-3646)

Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the sixth regular update.

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.

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)

The system must be rebooted for this update to take effect.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-1392 advisory.

  - The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a     reference count, which allows local users to cause a denial of service (memory consumption or system     crash) via a crafted application. (CVE-2013-4483)

  - The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing     socket operations based on the opener of a socket, which allows local users to bypass intended access     restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program. (CVE-2014-0181)

  - sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure     possession of a read/write lock, which allows local users to cause a denial of service (use-after-free)     and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.
    (CVE-2014-4653)

  - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux     kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows     local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by     leveraging /dev/snd/controlCX access for an ioctl call. (CVE-2014-4654)

  - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux     kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to     cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for     a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (CVE-2014-4655)

  - The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP     authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference     and OOPS) by starting to establish an association between two endpoints immediately after an exchange of     INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite     direction. (CVE-2014-5077)

  - The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the     number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a     denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a     large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn     value that leads to permanently pinned pages. (CVE-2014-3601)

  - The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly     consider which pages must be locked, which allows local users to cause a denial of service (system crash)     by triggering a memory-usage pattern that requires removal of page-table mappings. (CVE-2014-3122)

  - Integer overflow in the fb_mmap function in drivers/video/fbmem.c in the Linux kernel before 3.8.9, as     used in a certain Motorola build of Android 4.1.2 and other products, allows local users to create a read-     write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted     /dev/graphics/fb0 mmap2 system calls, as demonstrated by the Motochopper pwn program. (CVE-2013-2596)

  - ** DISPUTED ** Multiple integer overflows in the lzo1x_decompress_safe function in     lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-     dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. NOTE: the     author of the LZO algorithms says the Linux kernel is *not* affected; media hype. (CVE-2014-4608)

  - The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a     certain reference count during attempts to use the umount system call in conjunction with a symlink, which     allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have     unspecified other impact via the umount program. (CVE-2014-5045)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings (CVE-2014-3122).

Multiple stack-based buffer overflows in the magicmouse_raw_event function in drivers/hid/hid-magicmouse.c in the Magic Mouse HID driver in the Linux kernel through 3.16.3 allow physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with an event (CVE-2014-3181).

Array index error in the logi_dj_raw_event function in drivers/hid/hid-logitech-dj.c in the Linux kernel before 3.16.2 allows physically proximate attackers to execute arbitrary code or cause a denial of service (invalid kfree) via a crafted device that provides a malformed REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value (CVE-2014-3182).

The report_fixup functions in the HID subsystem in the Linux kernel before 3.16.2 might allow physically proximate attackers to cause a denial of service (out-of-bounds write) via a crafted device that provides a small report descriptor, related to (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, and (6) drivers/hid/hid-sunplus.c (CVE-2014-3184).

Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux kernel before 3.16.2 allow physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response (CVE-2014-3185).

Buffer overflow in the picolcd_raw_event function in devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the Linux kernel through 3.16.3, as used in Android on Nexus 7 devices, allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that sends a large report (CVE-2014-3186).

arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call (CVE-2014-3534).

The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages (CVE-2014-3601).

The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction (CVE-2014-5077).

The do_remount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a mount -o remount command within a user namespace (CVE-2014-5206).

Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry (CVE-2014-5471).

The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry (CVE-2014-5472).

The __udf_read_inode function in fs/udf/inode.c in the Linux kernel through 3.16.3 does not restrict the amount of ICB indirection, which allows physically proximate attackers to cause a denial of service (infinite loop or stack consumption) via a UDF filesystem with a crafted inode (CVE-2014-6410).

The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call (CVE-2014-7975).

The updated packages provides a solution for these security issues.
