Security Fix(es) :

  - A flaw was found in the way Linux kernel allocates heap     memory to build the scattergather list from a fragment     list(skb_shinfo(skb)->frag_list) in the socket     buffer(skb_buff). The heap overflow occurred if     'MAX_SKB_FRAGS

  - 1' parameter and 'NETIF_F_FRAGLIST' feature were used     together. A remote user or process could use this flaw     to potentially escalate their privilege on a system.
    (CVE-2017-7477, Important)

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel (denial of     service). (CVE-2017-7645, Important)

  - The NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the end     of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. (CVE-2017-7895,     Important)

  - The Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support was vulnerable to an     incorrect segment selector(SS) value error. The error     could occur while loading values into the SS register in     long mode. A user or process inside a guest could use     this flaw to crash the guest, resulting in DoS or     potentially escalate their privileges inside the guest.
    (CVE-2017-2583, Moderate)

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could allow     a remote attacker to force the kernel to enter a     condition in which it could loop indefinitely.
    (CVE-2017-6214, Moderate)

Bug Fix(es) :

  - Previously, the reserved-pages counter (HugePages_Rsvd)     was bigger than the total-pages counter     (HugePages_Total) in the /proc/meminfo file, and     HugePages_Rsvd underflowed. With this update, the     HugeTLB feature of the Linux kernel has been fixed, and     HugePages_Rsvd underflow no longer occurs.

  - If a directory on a NFS client was modified while being     listed, the NFS client could restart the directory     listing multiple times. Consequently, the performance of     listing the directory was sub-optimal. With this update,     the restarting of the directory listing happens less     frequently. As a result, the performance of listing the     directory while it is being modified has improved.

  - The Fibre Channel over Ethernet (FCoE) adapter in some     cases failed to reboot. This update fixes the qla2xxx     driver, and FCoE adapter now reboots as expected.

  - When a VM with Virtual Function I/O (VFIO) device was     rebooted, the QEMU process occasionally terminated     unexpectedly due to a failed VFIO Direct Memory Access     (DMA) map request. This update fixes the vfio driver and     QEMU no longer crashes in the described situation.

  - When the operating system was booted with the in-box     lpfc driver, a kernel panic occurred on the     little-endian variant of IBM Power Systems. This update     fixes lpfc, and the kernel no longer panics in the     described situation.

  - When creating or destroying a VM with Virtual Function     I/O (VFIO) devices with 'Hugepages' feature enabled,     errors in Direct Memory Access (DMA) page table entry     (PTE) mappings occurred, and QEMU memory usage behaved     unpredictably. This update fixes range computation when     making room for large pages in Input/Output Memory     Management Unit (IOMMU). As a result, errors in DMA PTE     mappings no longer occur, and QEMU has a predictable     memory usage in the described situation.

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

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472)

  - A reference counter leak in Linux kernel in     ipxitf_ioctl function was found which results in a use     after free vulnerability that's triggerable from     unprivileged userspace when IPX interface is     configured.(CVE-2017-7487)

  - A vulnerability was found in the Linux kernel where     filesystems mounted with data=ordered mode may allow an     attacker to read stale data from recently allocated     blocks in new files after a system 'reset' by abusing     ext4 mechanics of delayed allocation.(CVE-2017-7495)

  - 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-2017-7533)

  - 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-2017-7541)

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.(CVE-2017-7542)

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616)

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645)

  - The NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the     end of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.(CVE-2017-7895)

  - It was found that the NFSv4 server in the Linux kernel     did not properly validate layout type when processing     NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A     remote attacker could use this flaw to soft-lockup the     system and thus cause denial of service.(CVE-2017-8797)

  - A use-after-free vulnerability was found in DCCP socket     code affecting the Linux kernel since 2.6.16. This     vulnerability could allow an attacker to their escalate     privileges.(CVE-2017-8824)

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. 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 we     believe it is unlikely.(CVE-2017-8890)

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924)

  - The IPv6 fragmentation implementation in the Linux     kernel does not consider that the nexthdr field may be     associated with an invalid option, which allows local     users to cause a denial of service (out-of-bounds read     and BUG) or possibly have unspecified other impact via     crafted socket and send system calls. Due to the nature     of the flaw, privilege escalation cannot be fully ruled     out, although we believe it is unlikely.(CVE-2017-9074)

  - The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandles     inheritance, which allows local users to cause a denial     of service or possibly have unspecified other impact     via crafted system calls, a related issue to     CVE-2017-8890. 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 we believe it is unlikely.(CVE-2017-9075)

  - The IPv6 DCCP implementation in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. 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 we believe it is unlikely.(CVE-2017-9076)

  - The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandles     inheritance, which allows local users to cause a denial     of service or possibly have unspecified other impact     via crafted system calls, a related issue to     CVE-2017-8890. 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 we believe it is unlikely.(CVE-2017-9077)

  - The __ip6_append_data function in net/ipv6/ip6_output.c     in the Linux kernel through 4.11.3 is too late in     checking whether an overwrite of an skb data structure     may occur, which allows local users to cause a denial     of service (system crash) via crafted system     calls.(CVE-2017-9242)

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-1000004)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel, when an unspecified architecture and compiler     is used, might allow local users to cause a denial of     service by triggering an attempted use of the -INT_MIN     value.(CVE-2018-10087)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1647 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were adjacent to each other, an attacker could use this     flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on the system. This is a kernel-side mitigation which     increases the stack guard gap size from one page to 1 MiB to make successful exploitation of this issue     more difficult. (CVE-2017-1000364, Important)

    * The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in     an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make     these pointers point outside the array and cause an out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in denial of service. (CVE-2017-7645, Important)

    * The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lacked certain checks for     the end of a buffer. A remote attacker could trigger a pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3361-1 advisory.

    USN-3358-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04. This update provides the     corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04     LTS. Please note that this update changes the Linux HWE kernel to the 4.10 based kernel from Ubuntu 17.04,     superseding the 4.8 based HWE kernel from Ubuntu 16.10.

    Ben Harris discovered that the Linux kernel would strip extended privilege attributes of files when     performing a failed unprivileged system call. A local attacker could use this to cause a denial of     service. (CVE-2015-1350)

    Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel did not properly validate meta     block groups. An attacker with physical access could use this to specially craft an ext4 image that causes     a denial of service (system crash). (CVE-2016-10208)

    Peter Pi discovered that the colormap handling for frame buffer devices in the Linux kernel contained an     integer overflow. A local attacker could use this to disclose sensitive information (kernel memory).
    (CVE-2016-8405)

    It was discovered that an integer overflow existed in the InfiniBand RDMA over ethernet (RXE) transport     implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2016-8636)

    Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel.
    A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084)

    CAI Qian discovered that the sysctl implementation in the Linux kernel did not properly perform reference     counting in some situations. An unprivileged attacker could use this to cause a denial of service (system     hang). (CVE-2016-9191)

    It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent     special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use     this to bypass module verification. (CVE-2016-9604)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

This update for the Linux Kernel 3.12.61-52_83 fixes several issues.
The following security bugs were fixed :

  - CVE-2017-1000112: Prevent a race condition in net-packet     code that could have been exploited by unprivileged     users to gain root access (bsc#1052368).

  - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd     subsystem in the Linux kernel allowed remote attackers     to cause a denial of service (system crash) via a long     RPC reply (bsc#1046191).

  - CVE-2017-9242: The __ip6_append_data function in     net/ipv6/ip6_output.c in the Linux kernel was too late     in checking whether an overwrite of an skb data     structure may occur, which allowed local users to cause     a denial of service (system crash) via crafted system     calls (bsc#1042892).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
