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

  - The mq_notify function in the Linux kernel through     4.11.9 does not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allows attackers to cause a denial     of service (use-after-free) or possibly have     unspecified other impact.(CVE-2017-11176)

  - The brcmf_cfg80211_mgmt_tx function in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/     cfg80211.c in the Linux kernel before 4.12.3 allows     local users to cause a denial of service (buffer     overflow and system crash) or possibly gain privileges     via a crafted NL80211_CMD_FRAME Netlink     packet.(CVE-2017-7541)

  - The ip6_find_1stfragopt function in     net/ipv6/output_core.c in the Linux kernel through     4.12.3 allows local users to cause a denial of service     (integer overflow and infinite loop) by leveraging the     ability to open a raw socket.(CVE-2017-7542)

  - 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-2017-11473)

  - net/xfrm/xfrm_policy.c in the Linux kernel through     4.12.3, when CONFIG_XFRM_MIGRATE is enabled, does not     ensure that the dir value of xfrm_userpolicy_id is     XFRM_POLICY_MAX or less, which allows local users to     cause a denial of service (out-of-bounds access) or     possibly have unspecified other impact via an     XFRM_MSG_MIGRATE xfrm Netlink message.(CVE-2017-11600)

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604)

  - A user-controlled buffer is copied into a local buffer     of constant size using strcpy without a length check     which can cause a buffer overflow. This affects the     Linux kernel 4.9-stable tree, 4.12-stable tree,     3.18-stable tree, and 4.4-stable tree.(CVE-2017-12762)

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but does     not take the argument and environment pointers into     account, which allows attackers to bypass this     limitation. This affects Linux Kernel versions 4.11.5     and earlier. It appears that this feature was     introduced in the Linux Kernel version     2.6.23.(CVE-2017-1000365)

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

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2669 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 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, Important)

    * 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, Important)

    This update also fixes multiple Moderate and Low impact security issues:

    CVE-2017-8797 CVE-2015-8839 CVE-2016-9576 CVE-2016-7042 CVE-2016-7097 CVE-2016-8645 CVE-2016-9576     CVE-2016-9806 CVE-2016-10088 CVE-2017-2671 CVE-2017-5970 CVE-2017-6001 CVE-2017-6951 CVE-2017-7187     CVE-2017-7889 CVE-2017-8890 CVE-2017-9074 CVE-2017-8890 CVE-2017-9075 CVE-2017-8890 CVE-2017-9076     CVE-2017-8890 CVE-2017-9077 CVE-2016-9604 CVE-2016-9685

(bsc#1030593)

  - CVE-2016-9604: This fixes handling of keyrings starting     with '.' in KEYCTL_JOIN_SESSION_KEYRING, which could     have allowed local users to manipulate privileged     keyrings (bsc#1035576)

  - CVE-2017-7616: Incorrect error handling in the     set_mempolicy and mbind compat syscalls in     mm/mempolicy.c in the Linux kernel allowed local users     to obtain sensitive information from uninitialized stack     data by triggering failure of a certain bitmap     operation. (bnc#1033336).

  - 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, related to net/sunrpc/svc.c,     fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670).

  - CVE-2017-7308: The packet_set_ring function in     net/packet/af_packet.c in the Linux kernel did not     properly validate certain block-size data, which allowed     local users to cause a denial of service (overflow) or     possibly have unspecified other impact via crafted     system calls (bnc#1031579)

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently could not     ensure that disconnect function calls are safe, which     allowed local users to cause a denial of service (panic)     by leveraging access to the protocol value of     IPPROTO_ICMP in a socket system call (bnc#1031003)

  - CVE-2017-7294: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate addition of certain levels data,     which allowed local users to trigger an integer overflow     and out-of-bounds write, and cause a denial of service     (system hang or crash) or possibly gain privileges, via     a crafted ioctl call for a /dev/dri/renderD* device     (bnc#1031440)

  - CVE-2017-7261: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not check for a zero value of certain levels     data, which allowed local users to cause a denial of     service (ZERO_SIZE_PTR dereference, and GPF and possibly     panic) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031052)

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact via     a large command size in an SG_NEXT_CMD_LEN ioctl call,     leading to out-of-bounds write access in the sg_write     function (bnc#1030213)

  - CVE-2017-5669: The do_shmat function in ipc/shm.c in the     Linux kernel did not restrict the address calculated by     a certain rounding operation, which allowed local users     to map page zero, and consequently bypass a protection     mechanism that exists for the mmap system call, by     making crafted shmget and shmat system calls in a     privileged context (bnc#1026914).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415)

  - CVE-2016-10208: The ext4_fill_super function in     fs/ext4/super.c in the Linux kernel did not properly     validate meta block groups, which allowed physically     proximate attackers to cause a denial of service     (out-of-bounds read and system crash) via a crafted ext4     image (bnc#1023377).

  - CVE-2017-5897: The ip6gre_err function in     net/ipv6/ip6_gre.c in the Linux kernel allowed remote     attackers to have unspecified impact via vectors     involving GRE flags in an IPv6 packet, which trigger an     out-of-bounds access (bsc#1023762).

  - CVE-2017-5986: A race condition in the     sctp_wait_for_sndbuf function in net/sctp/socket.c in     the Linux kernel allowed local users to cause a denial     of service (assertion failure and panic) via a     multithreaded application that peels off an association     in a certain buffer-full state (bsc#1025235).

  - CVE-2017-6074: The dccp_rcv_state_process function in     net/dccp/input.c in the Linux kernel mishandled     DCCP_PKT_REQUEST packet data structures in the LISTEN     state, which allowed local users to obtain root     privileges or cause a denial of service (double free)     via an application that made an IPV6_RECVPKTINFO     setsockopt system call (bnc#1026024)

  - CVE-2016-9191: The cgroup offline implementation in the     Linux kernel mishandled certain drain operations, which     allowed local users to cause a denial of service (system     hang) by leveraging access to a container environment     for executing a crafted application (bnc#1008842)

  - CVE-2016-10044: The aio_mount function in fs/aio.c in     the Linux kernel did not properly restrict execute     access, which made it easier for local users to bypass     intended SELinux W^X policy restrictions, and     consequently gain privileges, via an io_setup system     call (bnc#1023992).

  - CVE-2016-3070: The trace_writeback_dirty_page     implementation in include/trace/events/writeback.h in     the Linux kernel improperly interacts with mm/migrate.c,     which allowed local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact by triggering a certain     page move (bnc#979215).

  - CVE-2016-5243: The tipc_nl_compat_link_dump function in     net/tipc/netlink_compat.c in the Linux kernel did not     properly copy a certain string, which allowed local     users to obtain sensitive information from kernel stack     memory by reading a Netlink message (bnc#983212).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did     not ensure that a certain destructor exists in required     circumstances, which allowed local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls (bnc#1027190)

  - CVE-2017-6346: Race condition in net/packet/af_packet.c     in the Linux kernel allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a multithreaded application     that made PACKET_FANOUT setsockopt system calls     (bnc#1027189)

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did     not properly restrict association peel-off operations     during certain wait states, which allowed local users to     cause a denial of service (invalid unlock and double     free) via a multithreaded application. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2017-5986 (bnc#1027066)

  - CVE-2017-5986: Race condition in the     sctp_wait_for_sndbuf function in net/sctp/socket.c in     the Linux kernel allowed local users to cause a denial     of service (assertion failure and panic) via a     multithreaded application that peels off an association     in a certain buffer-full state (bsc#1025235).

  - CVE-2017-6214: The tcp_splice_read function in     net/ipv4/tcp.c in the Linux kernel allowed remote     attackers to cause a denial of service (infinite loop     and soft lockup) via vectors involving a TCP packet with     the URG flag (bnc#1026722)

  - CVE-2016-2117: The atl2_probe function in     drivers/net/ethernet/atheros/atlx/atl2.c in the Linux     kernel incorrectly enables scatter/gather I/O, which     allowed remote attackers to obtain sensitive information     from kernel memory by reading packet data (bnc#968697)

  - CVE-2015-1350: The VFS subsystem in the Linux kernel     provided an incomplete set of requirements for setattr     operations that underspecifies removing extended     privilege attributes, which allowed local users to cause     a denial of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program (bsc#914939).

  - CVE-2016-7117: Use-after-free vulnerability in the
    __sys_recvmmsg function in net/socket.c in the Linux     kernel allowed remote attackers to execute arbitrary     code via vectors involving a recvmmsg system call that     is mishandled during error processing (bsc#1003077).
