The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2017-9074)

Note that Nessus relies on the presence of the package as reported by the vendor.

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-7482: Several missing length checks ticket     decode allowing for information leak or potentially code     execution (bsc#1046107).

  - CVE-2016-10277: Potential privilege escalation due to a     missing bounds check in the lp driver. A kernel     command-line adversary can overflow the parport_nr array     to execute code (bsc#1039456).

  - CVE-2017-7542: The ip6_find_1stfragopt function in     net/ipv6/output_core.c in the Linux kernel allowed local     users to cause a denial of service (integer overflow and     infinite loop) by leveraging the ability to open a raw     socket (bsc#1049882).

  - CVE-2017-7533: Bug in inotify code allowing privilege     escalation (bsc#1049483).

  - CVE-2017-11176: The mq_notify function in the Linux     kernel did not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allowed attackers to cause a denial     of service (use-after-free) or possibly have unspecified     other impact (bsc#1048275).

  - CVE-2017-11473: Buffer overflow in the     mp_override_legacy_irq() function in     arch/x86/kernel/acpi/boot.c in the Linux kernel allowed     local users to gain privileges via a crafted ACPI table     (bnc#1049603).

  - CVE-2017-1000365: The Linux Kernel imposed a size     restriction on the arguments and environmental strings     passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the     size), but did not take the argument and environment     pointers into account, which allowed attackers to bypass     this limitation.

  - CVE-2017-8925: The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel allowed     local users to cause a denial of service (tty     exhaustion) by leveraging reference count mishandling     (bnc#1038981).

  - CVE-2017-1000380: sound/core/timer.c was vulnerable to a     data race in the ALSA /dev/snd/timer driver resulting in     local users being able to read information belonging to     other users, i.e., uninitialized memory contents could     have bene disclosed when a read and an ioctl happen at     the same time (bnc#1044125)

  - CVE-2017-9242: The __ip6_append_data function in     net/ipv6/ip6_output.c 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 (bnc#1041431)

  - CVE-2017-1000363: A buffer overflow in kernel     commandline handling of the 'lp' parameter could be used     by local console attackers to bypass certain secure boot     settings. (bnc#1039456)

  - CVE-2017-9076: The dccp_v6_request_recv_sock function in     net/dccp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1039885)

  - CVE-2017-9077: The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1040069)

  - CVE-2017-9075: The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1039883)

  - CVE-2017-7487: The ipxitf_ioctl function in     net/ipx/af_ipx.c in the Linux kernel mishandled     reference counts, which allowed 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 (bnc#1038879)

  - CVE-2017-8890: The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allowed attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call (bnc#1038544)

  - CVE-2017-2647: The KEYS subsystem in the Linux kernel     allowed local users to gain privileges or cause a denial     of service (NULL pointer dereference and system crash)     via vectors involving a NULL value for a certain match     field, related to the keyring_search_iterator function     in keyring.c (bnc#1030593)

  - CVE-2017-6951: The keyring_search_aux function in     security/keys/keyring.c in the Linux kernel allowed     local users to cause a denial of service (NULL pointer     dereference and OOPS) via a request_key system call for     the 'dead' type (bnc#1029850)

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2018-0015 for details.

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
