Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update for qemu-kvm-rhev is now available for RHEV 4.X RHEV-H and Agents for RHEL 7.

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.

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-based 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.

  - CVE-2016-7909: The pcnet_rdra_addr function in     hw/net/pcnet.c allowed local guest OS administrators to     cause a denial of service (infinite loop and QEMU     process crash) by setting the (1) receive or (2)     transmit descriptor ring length to 0 (bsc#1002557).

  - CVE-2016-9101: eepro100 memory leakage whern unplugging     a device (bsc#1007391).

  - CVE-2016-8910: The rtl8139_cplus_transmit function in     hw/net/rtl8139.c allowed local guest OS administrators     to cause a denial of service (infinite loop and CPU     consumption) by leveraging failure to limit the ring     descriptor count (bsc#1006538).

  - CVE-2016-8909: The intel_hda_xfer function in     hw/audio/intel-hda.c allowed local guest OS     administrators to cause a denial of service (infinite     loop and CPU consumption) via an entry with the same     value for buffer length and pointer position     (bsc#1006536).

  - CVE-2016-7994: Memory leak in     virtio_gpu_resource_create_2d (bsc#1003613).
