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.

Several vulnerabilities were discovered in qemu, a fast processor emulator. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2016-7909

Quick Emulator(Qemu) built with the AMD PC-Net II emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets via pcnet_receive().

A privileged user/process inside guest could use this issue to crash the Qemu process on the host leading to DoS.

CVE-2016-8909

Quick Emulator(Qemu) built with the Intel HDA controller emulation support is vulnerable to an infinite loop issue. It could occur while processing the DMA buffer stream while doing data transfer in 'intel_hda_xfer'.

A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host, resulting in DoS.

CVE-2016-8910

Quick Emulator(Qemu) built with the RTL8139 ethernet controller emulation support is vulnerable to an infinite loop issue. It could occur while transmitting packets in C+ mode of operation.

A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host, resulting in DoS situation.

CVE-2016-9101

Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is vulnerable to a memory leakage issue. It could occur while unplugging the device, and doing so repeatedly would result in leaking host memory affecting, other services on the host.

A privileged user inside guest could use this flaw to cause a DoS on the host and/or potentially crash the Qemu process on the host.

CVE-2016-9102 CVE-2016-9105 CVE-2016-9106

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to a several memory leakage issues.

A privileged user inside guest could use this flaws to leak the host memory bytes resulting in DoS for other services.

CVE-2016-9104

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an integer overflow issue. It could occur by accessing xattributes values.

A privileged user inside guest could use this flaw to crash the Qemu process instance resulting in DoS.

CVE-2016-9103

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an information leakage issue. It could occur by accessing xattribute value before it's written to.

A privileged user inside guest could use this flaw to leak host memory bytes.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u18.

We recommend that you upgrade your qemu packages.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Memory leak in the v9fs_xattrcreate function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local     guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) via a     large number of Txattrcreate messages with the same fid number. (CVE-2016-9102)

Note that Nessus relies on the presence of the package as reported by the vendor.
