The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2931 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):

    * Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming     packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write     and privilege escalation. (CVE-2017-7184, Important)

    * 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) could use this flaw to elevate their privileges on     the system. (CVE-2017-1000111, Important)

    * An exploitable memory corruption flaw was found in the Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw can be exploited to gain root privileges.
    (CVE-2017-1000112, Important)

    * A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN     capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header     and sending to its destination via sendto(). (CVE-2016-8399, Moderate)

    * 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, Moderate)

    * 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, Moderate)

    * A kernel data leak due to an out-of-bound read was found in the Linux kernel in     inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through     version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export     socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a     userspace. (CVE-2017-7558, Moderate)

    * 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 possibly     cause a situation where a value may be used after being freed (use-after-free) which may lead to memory     corruption or other unspecified other impact. (CVE-2017-11176, Moderate)

    * A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate)

    Red Hat would like to thank Chaitin Security Research Lab for reporting CVE-2017-7184; Willem de Bruijn     for reporting CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112. The CVE-2017-7558     issue was discovered by Stefano Brivio (Red Hat).

    Bug Fix(es):

    * The kernel-rt packages have been upgraded to the 3.10.0-693.5.2 source tree, which provides number of     bug fixes over the previous version. (BZ#1489084)

The remote OracleVM system is missing necessary patches to address critical security updates :

  - ipv6: avoid overflow of offset in ip6_find_1stfragopt     (Sabrina Dubroca) [Orabug: 27011255] (CVE-2017-7542)

  - udp: consistently apply ufo or fragmentation (Willem de     Bruijn) [Orabug: 26921320] (CVE-2017-1000112)

An update for kernel is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* 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) could use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important)

* A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate)

Red Hat would like to thank Willem de Bruijn for reporting CVE-2017-1000111 and Andrey Konovalov for reporting CVE-2017-1000112.

Bug Fix(es) :

* When the operating system was booted with Red Hat Enterprise Virtualization, and the eh_deadline sysfs parameter was set to 10s, the Storage Area Network (SAN) issues caused eh_deadline to trigger with no handler. Consequently, a kernel panic occurred. This update fixes the lpfc driver, thus preventing the kernel panic under described circumstances. (BZ #1487220)

* When an NFS server returned the NFS4ERR_BAD_SEQID error to an OPEN request, the open-owner was removed from the state_owners rbtree.
Consequently, NFS4 client infinite loop that required a reboot to recover occurred. This update changes NFS4ERR_BAD_SEQID handling to leave the open-owner in the state_owners rbtree by updating the create_time parameter so that it looks like a new open-owner. As a result, an NFS4 client is now able to recover without falling into the infinite recovery loop after receiving NFS4ERR_BAD_SEQID. (BZ#1491123)

* If an NFS client attempted to mount NFSv3 shares from an NFS server exported directly to the client's IP address, and this NFS client had already mounted other shares that originated from the same server but were exported to the subnetwork which this client was part of, the auth.unix.ip cache expiration was not handled correctly. Consequently, the client received the 'stale file handle' errors when trying to mount the share. This update fixes handling of the cache expiration, and the NFSv3 shares now mount as expected without producing the 'stale file handle' errors. (BZ #1497976)

* When running a script that raised the tx ring count to its maximum value supported by the Solarflare Network Interface Controller (NIC) driver, the EF10 family NICs allowed the settings exceeding the hardware's capability. Consequently, the Solarflare hardware became unusable with Red Hat Entepripse Linux 6. This update fixes the sfc driver, so that the tx ring can have maximum 2048 entries for all EF10 NICs. As a result, the Solarflare hardware no longer becomes unusable with Red Hat Entepripse Linux 6 due to this bug. (BZ#1498019)

    (CVE-2017-1000112, Important)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service. (CVE-2017-14106, Moderate)

Bug Fix(es) :

  - When the operating system was booted with RHEV/oVirt,     and the eh_deadline sysfs parameter was set to 10s, the     Storage Area Network (SAN) issues caused eh_deadline to     trigger with no handler. Consequently, a kernel panic     occurred. This update fixes the lpfc driver, thus     preventing the kernel panic under described     circumstances.

As a result, the Solarflare     hardware no longer becomes unusable.

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2018-0035 for details.

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

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754)

  - A flaw was found in the Linux kernel's implementation     of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()     system call. Users with non-namespace CAP_NET_ADMIN are     able to trigger this call and create a situation in     which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and     create situations where the system could crash or cause     memory corruption.(CVE-2016-9793)

  - A use-after-free vulnerability was found in ALSA pcm     layer, which allows local users to cause a denial of     service, memory corruption, or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9794)

  - A double free vulnerability was found in netlink_dump,     which could cause a denial of service or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9806)

  - 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)

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112)

  - A stack buffer overflow flaw was found in the way the     Bluetooth subsystem of the Linux kernel processed     pending L2CAP configuration responses from a client. On     systems with the stack protection feature enabled in     the kernel (CONFIG_CC_STACKPROTECTOR=y, which is     enabled on all architectures other than s390x and     ppc64le), an unauthenticated attacker able to initiate     a connection to a system via Bluetooth could use this     flaw to crash the system. Due to the nature of the     stack protection feature, code execution cannot be     fully ruled out, although we believe it is unlikely. On     systems without the stack protection feature (ppc64le     the Bluetooth modules are not built on s390x), an     unauthenticated attacker able to initiate a connection     to a system via Bluetooth could use this flaw to     remotely execute arbitrary code on the system with ring     0 (kernel) privileges.(CVE-2017-1000251)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (i1/4z1024) index value.(CVE-2017-1000252)

  - 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)

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this     limitation.(CVE-2017-1000365)

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410)

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or     use-after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.(CVE-2017-10661)

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810)

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911)

  - A use-after-free flaw was found in the Netlink     functionality of the Linux kernel networking subsystem.
    Due to the insufficient cleanup in the mq_notify     function, a local attacker could potentially use this     flaw to escalate their privileges on the     system.(CVE-2017-11176)

  - 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)

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service     (out-of-bounds access) or possibly have unspecified     other impact by sending a XFRM_MSG_MIGRATE netlink     message. This flaw is present in the Linux kernel since     an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up     to 4.13-rc3.(CVE-2017-11600)

  - A security flaw was discovered in     nl80211_set_rekey_data() function in the Linux kernel     since v3.1-rc1 through v4.13. This function does not     check whether the required attributes are present in a     netlink request. This request can be issued by a user     with CAP_NET_ADMIN privilege and may result in NULL     dereference and a system crash.(CVE-2017-12153)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a     nested visualization setup, L2 guest user could use     this flaw to potentially crash the host(L0) resulting     in DoS.(CVE-2017-12154)

  - The Linux kernel built with the KVM visualization     support (CONFIG_KVM), with nested visualization(nVMX)     feature enabled (nested=1), was vulnerable to a stack     buffer overflow issue. The vulnerability could occur     while traversing guest page table entries to resolve     guest virtual address(gva). An L1 guest could use this     flaw to crash the host kernel resulting in denial of     service (DoS) or potentially execute arbitrary code on     the host to gain privileges on the     system.(CVE-2017-12188)
