The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3472 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):

    * An assertion-failure flaw was found in the Network Block Device (NBD) server's initial connection     negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent     unexpected data during connection negotiation. A remote user or process could use this flaw to crash the     qemu-nbd server resulting in denial of service. (CVE-2017-7539)

    * Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash     via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during     negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server     resulting in a Denial of Service (DoS). (CVE-2017-10664)

    * Quick Emulator (QEMU), compiled with qemu_map_ram_ptr to access guests' RAM block area, is vulnerable to     an OOB r/w access issue. The crash can occur if a privileged user inside a guest conducts certain DMA     operations, resulting in a DoS. (CVE-2017-11334)

    * Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is     vulnerable to an OOB r/w memory access issue. The issue could occur due to an integer overflow while     loading a kernel image during a guest boot. A user or process could use this flaw to potentially achieve     arbitrary code execution on a host. (CVE-2017-14167)

    * Quick emulator (QEMU), compiled with the Cirrus CLGD 54xx VGA Emulator support, is vulnerable to an OOB     write access issue. The issue could occur while writing to VGA memory via mode4and5 write functions. A     privileged user inside guest could use this flaw to crash the QEMU process resulting in Denial of Serivce     (DoS). (CVE-2017-15289)

    Red Hat would like to thank Alex for reporting CVE-2017-11334; Thomas Garnier (Google.com) for reporting     CVE-2017-14167; and Guoxiang Niu (Huawei.com) for reporting CVE-2017-15289.

    Bug Fix(es):

    * Hot-unplugging Virtual Function I/O (VFIO) devices previously failed when performed after hot-unplugging     a vhost network device. This update fixes the underlying code, and the VFIO device is unplugged correctly     in the described circumstances. (BZ#1498139)
