The arch_dup_task_struct function in the Transactional Memory (TM) implementation in arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly interact with the clone and fork system calls, which allows local users to cause a denial of service (Program Check and system crash) via certain instructions that are executed with the processor in the Transactional state.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A memory corruption flaw was found in the way the USB     ConnectTech WhiteHEAT serial driver processed     completion commands sent via USB Request Blocks     buffers. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3185i1/4%0

  - Use-after-free vulnerability in the msm_set_crop     function in drivers/media/video/msm/msm_camera.c in the     MSM-Camera driver for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, allows attackers to     gain privileges or cause a denial of service (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2015-0568i1/4%0

  - The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel through 4.3.3 does not initialize a certain     structure member, which allows local users to obtain     sensitive information from kernel memory via a crafted     application.(CVE-2015-7884i1/4%0

  - The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel can allow     a local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16535i1/4%0

  - The ACPI parsing functionality in the Linux kernel does     not flush the node and node_ext caches which causes a     kernel stack dump. This allows local users to obtain     sensitive information from kernel memory and use this     information to bypass the KASLR protection mechanism by     creating and applying crafted ACPI     table.(CVE-2017-13694i1/4%0

  - The is_ashmem_file function in     drivers/staging/android/ashmem.c in a certain Qualcomm     Innovation Center (QuIC) Android patch for the Linux     kernel 3.x mishandles pointer validation within the     KGSL Linux Graphics Module, which allows attackers to     bypass intended access restrictions by using the     /ashmem string as the dentry name.(CVE-2016-5340i1/4%0

  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312i1/4%0

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. An unprivileged local user could use this     flaw to induce kernel memory corruption on the system,     leading to a crash. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although it is unlikely.(CVE-2017-7541i1/4%0

  - A flaw in the netback module allowed frontends to     control mapping of requests to request queues. An     attacker can change this mapping by requesting invalid     mapping requests allowing the (usually privileged)     backend to access out-of-bounds memory access for     reading and writing.(CVE-2018-15471i1/4%0

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633i1/4%0

  - It was found that the Linux kernel can hit a BUG_ON()     statement in the __xfs_get_blocks() in the     fs/xfs/xfs_aops.c because of a race condition between     direct and memory-mapped I/O associated with a hole in     a file that is handled with BUG_ON() instead of an I/O     failure. This allows a local unprivileged attacker to     cause a system crash and a denial of     service.(CVE-2016-10741i1/4%0

  - A vulnerability was found in the Linux kernel. The     pointer to the netlink socket attribute is not checked,     which could cause a null pointer dereference when     parsing the nested attributes in function     tipc_nl_publ_dump(). This allows local users to cause a     DoS.(CVE-2016-4951i1/4%0

  - It was reported that with Linux kernel, earlier than     version v4.10-rc8, an application may trigger a BUG_ON     in sctp_wait_for_sndbuf if the socket tx buffer is     full, a thread is waiting on it to queue more data, and     meanwhile another thread peels off the association     being used by the first thread.(CVE-2017-5986i1/4%0

  - The kvm_vm_ioctl_check_extension function in     arch/powerpc/kvm/powerpc.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) via a     KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to     /dev/kvm.(CVE-2017-15306i1/4%0

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830i1/4%0

  - A flaw was found in the way the Linux kernel's SCTP     implementation validated INIT chunks when performing     Address Configuration Change (ASCONF). A remote     attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a     NULL pointer dereference on the     system.(CVE-2014-7841i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - A flaw was found in the way the Linux kernel performed     forking inside of a transaction. A local, unprivileged     user on a PowerPC system that supports transactional     memory could use this flaw to crash the     system.(CVE-2014-2673i1/4%0

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569i1/4%0

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-0290 advisory.

  - arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not     ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS     users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm     access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. (CVE-2014-3690)

  - The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows     local users to cause a denial of service (memory corruption or system crash) by accessing certain memory     locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage     migration, related to fs/proc/task_mmu.c and mm/mempolicy.c. (CVE-2014-3940)

  - kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall     numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-     bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application. (CVE-2014-7825)

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

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

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

* It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory.
(CVE-2014-3534, Important)

* 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 a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate)

* A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system. (CVE-2014-2673, Moderate)

* A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate)

* An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made.
(CVE-2014-4667, Moderate)

Red Hat would like to thank Martin Schwidefsky of IBM for reporting CVE-2014-3534, Andy Lutomirski for reporting CVE-2014-0181, and Gopal Reddy Kodudula of Nokia Siemens Networks for reporting CVE-2014-4667.

This update also fixes the following bugs :

* Due to a NULL pointer dereference bug in the IPIP and SIT tunneling code, a kernel panic could be triggered when using IPIP or SIT tunnels with IPsec. This update restructures the related code to avoid a NULL pointer dereference and the kernel no longer panics when using IPIP or SIT tunnels with IPsec. (BZ#1114957)

* Previously, an IBM POWER8 system could terminate unexpectedly when the kernel received an IRQ while handling a transactional memory re-checkpoint critical section. This update ensures that IRQs are disabled in this situation and the problem no longer occurs.
(BZ#1113150)

* A missing read memory barrier, rmb(), in the bnx2x driver caused the kernel to crash under various circumstances. This problem has been fixed by adding an rmb() call to the relevant place in the bnx2x code.
(BZ#1107721)

* The hpwdt driver previously emitted a panic message that was misleading on certain HP systems. This update ensures that upon a kernel panic, hpwdt displays information valid on all HP systems.
(BZ#1096961)

* The qla2xxx driver has been upgraded to version 8.06.00.08.07.0-k3, which provides a number of bug fixes over the previous version in order to correct various timeout problems with the mailbox commands.
(BZ#1112389)

* The SCSI mid-layer could retry an I/O operation indefinitely if a storage array repeatedly returned a CHECK CONDITION status to that I/O operation but the sense data was invalid. This update fixes the problem by limiting a time for which is such an I/O operation retried.
(BZ#1114468)

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.

  - 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)

  - The arch_dup_task_struct function in the Transactional Memory (TM) implementation in     arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly     interact with the clone and fork system calls, which allows local users to cause a denial of service     (Program Check and system crash) via certain instructions that are executed with the processor in the     Transactional state. (CVE-2014-2673)

  - 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 sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not     properly manage a certain backlog value, which allows remote attackers to cause a denial of service     (socket outage) via a crafted SCTP packet. (CVE-2014-4667)

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