The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-1276:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any     Linux operating system.  The kernel handles the basic functions     of the operating system: memory allocation, process allocation, device     input and output, etc.
    Security issues fixed with this release:
    CVE-2016-6828     The tcp_check_send_head function in include/net/tcp.h in the Linux     kernel before 4.7.5 does not properly maintain certain SACK state     after a failed data copy, which allows local users to cause a denial     of service (tcp_xmit_retransmit_queue use-after-free and system crash)     via a crafted SACK option.
    CVE-2016-7117     Use-after-free vulnerability in the __sys_recvmmsg function in     net/socket.c in the Linux kernel before 4.5.2 allows remote attackers     to execute arbitrary code via vectors involving a recvmmsg system call     that is mishandled during error processing.
    CVE-2016-9555     The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux     kernel before 4.8.8 lacks chunk-length checking for the first chunk,     which allows remote attackers to cause a denial of service     (out-of-bounds slab access) or possibly have unspecified other impact     via crafted SCTP data.
    Fixed bugs:
    * Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a     conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached     by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO     problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been     improved.
    * Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition     between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted.
    This update fixes the race condition. As a result, the operating system no longer reboots in the described     situation.
    * Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number     of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and     the packet loss no longer occurs in the described situation.
    * Previously, the virtual network devices contained in the deleted namespace could be deleted in any     order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan     devices, could end up with dangling references to the loopback device. Consequently, deleting a network     namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has     been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a     result, the kernel oops no longer occurs under the described circumstances.
    * Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of     0xA149 showed the following warning messages during the boot:
    Unknown Intel PCH (0xa149) detected. Warning: Intel Kabylake processor with unknown PCH - this hardware     has not undergone testing by Red Hat and might not be certified. Please consult     https://hardware.redhat.comfor certified hardware.
    * Previously, the operating system occasionally became unresponsive after a long run. This was caused by a     race condition between the try_to_wake_up() function and a woken up task in the core scheduler. With this     update, the race condition has been fixed, and the operating system no longer locks up in the described     scenario.
    These updated kernel packages include several security issues and numerous bug fixes, some of which you     can see below.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3161-2 advisory.

    USN-3161-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the     corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu     14.04 LTS.

    Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the TTY implementation in the     Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
    (CVE-2015-8964)

    It was discovered that the Video For Linux Two (v4l2) implementation in the Linux kernel did not properly     handle multiple planes when processing a VIDIOC_DQBUF ioctl(). A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-4568)

    CAI Qian discovered that shared bind mounts in a mount namespace exponentially added entries without     restriction to the Linux kernel's mount table. A local attacker could use this to cause a denial of     service (system crash). (CVE-2016-6213)

    It was discovered that the KVM implementation for x86/x86_64 in the Linux kernel could dereference a null     pointer. An attacker in a guest virtual machine could use this to cause a denial of service (system crash)     in the KVM host. (CVE-2016-8630)

    Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a     buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute     arbitrary code with administrative privileges. (CVE-2016-8633)

    Marco Grassi discovered that the TCP implementation in the Linux kernel mishandles socket buffer (skb)     truncation. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-8645)

    Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation     of incoming data. A remote attacker could use this to cause a denial of service (system crash).
    (CVE-2016-9555)

According to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - 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 can allow     a remote attacker to force the kernel to enter a     condition in which it can loop indefinitely.

  - It was discovered that a remote attacker could leverage     the generation of IPv6 atomic fragments to trigger the     use of fragmentation in an arbitrary IPv6 flow (in     scenarios in which actual fragmentation of packets is     not needed) and could subsequently perform any type of     a fragmentation-based attack against legacy IPv6 nodes     that do not implement RFC6946.

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.

  - A flaw was found in the Linux kernel's implementation     of the SCTP protocol. A remote attacker could trigger     an out-of-bounds read with an offset of up to 64kB     potentially causing the system to crash.

  - 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().

  - It was found that when file permissions were modified     via chmod and the user modifying them was not in the     owning group or capable of CAP_FSETID, the setgid bit     would be cleared. Setting a POSIX ACL via setxattr sets     the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way. This     could allow a local user to gain group privileges via     certain setgid applications.

  - It was found that when the gcc stack protector was     enabled, reading the /proc/keys file could cause a     panic in the Linux kernel due to stack corruption. This     happened because an incorrect buffer size was used to     hold a 64-bit timeout value rendered as weeks.

  - A race condition flaw was found in the ioctl_send_fib()     function in the Linux kernel's aacraid implementation.
    A local attacker could use this flaw to cause a denial     of service (out-of-bounds access or system crash) by     changing a certain size value.

  - When creating audit records for parameters to executed     children processes, an attacker can convince the Linux     kernel audit subsystem can create corrupt records which     may allow an attacker to misrepresent or evade logging     of executing commands.

  - A flaw was discovered in the way the Linux kernel dealt     with paging structures. When the kernel invalidated a     paging structure that was not in use locally, it could,     in principle, race against another CPU that is     switching to a process that uses the paging structure     in question. A local user could use a thread running     with a stale cached virtual->physical translation to     potentially escalate their privileges if the     translation in question were writable and the physical     page got reused for something critical (for example, a     page table).

  - A flaw was found in the USB-MIDI Linux kernel driver: a     double-free error could be triggered for the 'umidi'     object. An attacker with physical access to the system     could use this flaw to escalate their privileges.
