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

  - The regulator_ena_gpio_free function in     drivers/regulator/core.c in the Linux kernel allows     local users to gain privileges or cause a denial of     service (use-after-free) via a crafted     application.i1/4^CVE-2014-9940i1/4%0

  - Race condition in the sctp_wait_for_sndbuf function in     net/sctp/socket.c in the Linux kernel before 4.9.11     allows 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.i1/4^CVE-2017-5986i1/4%0

  - net/sctp/socket.c in the Linux kernel through 4.10.1     does not properly restrict association peel-off     operations during certain wait states, which allows     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.i1/4^CVE-2017-6353i1/4%0

  - The ipxitf_ioctl function in net/ipx/af_ipx.c in the     Linux kernel through 4.11.1 mishandles reference     counts, which allows local users to cause a denial of     service (use-after-free) or possibly have unspecified     other impact via a failed SIOCGIFADDR ioctl call for an     IPX interface.i1/4^CVE-2017-7487i1/4%0

  - fs/ext4/inode.c in the Linux kernel before 4.6.2, when     ext4 data=ordered mode is used, mishandles a     needs-flushing-before-commit list, which allows local     users to obtain sensitive information from other users'     files in opportunistic circumstances by waiting for a     hardware reset, creating a new file, making write     system calls, and reading this file.i1/4^CVE-2017-7495i1/4%0

  - The NFSv2/NFSv3 server in the nfsd subsystem in the     Linux kernel through 4.10.11 allows 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.i1/4^CVE-2017-7645i1/4%0

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     through 4.10.15 allows attackers to cause a denial of     service (double free) or possibly have unspecified     other impact by leveraging use of the accept system     call.i1/4^CVE-2017-8890i1/4%0

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel before     4.10.4 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.i1/4^CVE-2017-8924i1/4%0

  - The IPv6 fragmentation implementation in the Linux     kernel through 4.11.1 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.i1/4^CVE-2017-9074i1/4%0

  - The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel through 4.11.1     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.i1/4^CVE-2017-9075i1/4%0

  - The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel through 4.11.1     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.i1/4^CVE-2017-9077i1/4%0

  - 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.i1/4^CVE-2017-9242i1/4%0

  - The ext4_fill_super function in fs/ext4/super.c in the     Linux kernel through 4.9.8 does not properly validate     meta block groups, which allows physically proximate     attackers to cause a denial of service (out-of-bounds     read and system crash) via a crafted ext4     image.i1/4^CVE-2016-10208i1/4%0

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1842 advisory.

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

    Security Fix(es):

    * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system.
    (CVE-2016-10200, Important)

    * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A     local user could use this flaw to crash the system or, potentially, escalate their privileges.
    (CVE-2017-2647, 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-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042, CVE-2016-7097, CVE-2016-8645, CVE-2016-9576,     CVE-2016-9588, CVE-2016-9806, CVE-2016-10088, CVE-2016-10147, CVE-2017-2596, CVE-2017-2671, CVE-2017-5970,     CVE-2017-6001, CVE-2017-6951, CVE-2017-7187, CVE-2017-7616, 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-2017-9242,     CVE-2014-7970, CVE-2014-7975, CVE-2016-6213, CVE-2016-9604, CVE-2016-9685

    Documentation for these issues is available from the Release Notes document linked from the References     section.
