The remote host is affected by the vulnerability described in GLSA-201611-11 (QEMU: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in QEMU. Please review the       CVE identifiers referenced below for details.
  Impact :

    A privileged user /process within a guest QEMU environment can cause a       Denial of Service condition against the QEMU guest process or the host.
  Workaround :

    There is no known workaround at this time.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2408 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of     architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines     that use KVM in environments managed by Red Hat products.

    Security Fix(es):

    * Quick Emulator (QEMU) built with Network Block Device (NBD) Server support was vulnerable to a null-     pointer dereference issue. The flaw could occur when releasing a client that was not initialized due to     failed negotiation. A remote user or process could exploit this flaw to crash the qemu-nbd server (denial     of service). (CVE-2017-9524)

    * An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)     optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user     inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020)

    * A memory-leak flaw was found in the Quick Emulator (QEMU) built with USB xHCI controller emulation     support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly     resulted in leaking host memory, which affected other services on the host. A privileged user inside the     guest could exploit this flaw to cause a denial of service on the host or potentially crash the host's     QEMU process instance. (CVE-2016-7466)

    * Multiple CVEs were fixed as a result of rebase to QEMU 2.9.0. (CVE-2016-6888, CVE-2016-7422,     CVE-2016-8576, CVE-2016-8669, CVE-2016-8909, CVE-2016-8910, CVE-2016-9907, CVE-2016-9911, CVE-2016-9921,     CVE-2016-9922, CVE-2016-10155, CVE-2017-5579, CVE-2017-5973, CVE-2017-6414, CVE-2017-8309, CVE-2017-8379,     CVE-2017-9310, CVE-2017-9373, CVE-2017-9374, CVE-2017-9375)

CVE-2017-10664

Denial of service in the qemu-nbd (QEMU Disk Network Block Device) Server.

CVE-2018-10839 / CVE-2018-17962 / CVE-2018-17963

Daniel Shapira reported several integer overflows in the packet handling in ethernet controllers emulated by QEMU. These issues could lead to denial of service.

This updates xen to version 4.5.5 to fix the following issues :

  - An unprivileged user in a guest could gain guest could     escalate privilege to that of the guest kernel, if it     had could invoke the instruction emulator. Only 64-bit     x86 HVM guest were affected. Linux guest have not been     vulnerable. (boo#1016340, CVE-2016-10013)

  - An unprivileged user in a 64 bit x86 guest could gain     information from the host, crash the host or gain     privilege of the host (boo#1009107, CVE-2016-9383)

  - An unprivileged guest process could (unintentionally or     maliciously) obtain or ocorrupt sensitive information of     other programs in the same guest.

  - A malicious guest administrator could escalate their     privilege to that of the host. Only affects x86 HVM     guests using qemu older version 1.6.0 or using the     qemu-xen-traditional. (boo#1011652, CVE-2016-9637)

  - An unprivileged guest user could escalate privilege to     that of the guest administrator on x86 HVM guests,     especially on Intel CPUs (boo#1009100, CVE-2016-9386)

  - An unprivileged guest user could escalate privilege to     that of the guest administrator (on AMD CPUs) or crash     the system (on Intel CPUs) on 32-bit x86 HVM guests.
    Only guest operating systems that allowed a new task to     start in VM86 mode were affected. (boo#1009103,     CVE-2016-9382)

  - A malicious guest administrator could crash the host on     x86 PV guests only (boo#1009104, CVE-2016-9385)

    (boo#1009109, CVE-2016-9381)

  - A vulnerability in pygrub allowed a malicious guest     administrator to obtain the contents of sensitive host     files, or even delete those files (boo#1009111,     CVE-2016-9379, CVE-2016-9380)

  - A privileged guest user could cause an infinite loop in     the RTL8139 ethernet emulation to consume CPU cycles on     the host, causing a DoS situation (boo#1007157,     CVE-2016-8910)

  - A privileged guest user could cause an infinite loop in     the intel-hda sound emulation to consume CPU cycles on     the host, causing a DoS situation (boo#1007160,     CVE-2016-8909)

  - A privileged guest user could cause a crash of the     emulator process on the host by exploiting a divide by     zero vulnerability of the JAZZ RC4030 chipset emulation     (boo#1005004 CVE-2016-8667)

  - A privileged guest user could cause a crash of the     emulator process on the host by exploiting a divide by     zero issue of the 16550A UART emulation (boo#1005005,     CVE-2016-8669)

This update was imported from the SUSE:SLE-12-SP1:Update update project.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2392 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of     architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines     that use KVM in environments managed by Red Hat products.

    The following packages have been upgraded to a later upstream version: qemu-kvm-rhev (2.9.0). (BZ#1387372,     BZ#1387600, BZ#1400962)

    Security Fix(es):

    * A stack buffer overflow flaw was found in the Quick Emulator (QEMU) built with the Network Block Device     (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request.
    A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially     execute arbitrary code on client host with privileges of the QEMU process. (CVE-2017-2630)

    * An integer overflow flaw was found in Quick Emulator (QEMU) in the CCID Card device support. The flaw     could occur while passing messages via command/response packets to and from the host. A privileged user     inside a guest could use this flaw to crash the QEMU process. (CVE-2017-5898)

    * An information exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)     optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user     inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020)

    * A memory-leak flaw was found in the Quick Emulator(QEMU) built with USB xHCI controller emulation     support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly     resulted in leaking host memory, affecting other services on the host. A privileged user inside the guest     could exploit this flaw to cause a denial of service on the host or potentially crash the host's QEMU     process instance. (CVE-2016-7466)

    * Multiple CVEs(CVE-2016-10155, CVE-2016-4020, CVE-2016-6835, CVE-2016-6888, CVE-2016-7422, CVE-2016-7466,     CVE-2016-8576, CVE-2016-8669, CVE-2016-8909, CVE-2016-8910, CVE-2016-9907, CVE-2016-9911, CVE-2016-9921,     CVE-2016-9922, CVE-2017-2630, CVE-2017-5579, CVE-2017-5898, CVE-2017-5973, CVE-2017-9310, CVE-2017-9373,     CVE-2017-9374, CVE-2017-9375) were fixed as result of rebase to QEMU version 2.9.0.
