qemu-kvm - security update

Multiple vulnerabilities have been found in qemu-kvm:

• CVE-2016-7161
  Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite
  in qemu-kvm allows attackers to execute arbitrary code on the QEMU host via
  a large ethlite packet.
• CVE-2016-7170
  The vmsvga_fifo_run function in hw/display/vmware_vga.c in qemu-kvm is
  vulnerable to an OOB memory access.
• CVE-2016-7908
  The mcf_fec_do_tx function in hw/net/mcf_fec.c in qemu-kvm does not
  properly limit the buffer descriptor count when transmitting packets, which
  allows local guest OS administrators to cause a denial of service (infinite
  loop and QEMU process crash) via vectors involving a buffer descriptor with
  a length of 0 and crafted values in bd.flags.

For Debian 7 Wheezy, these problems have been fixed in version
1.1.2+dfsg-6+deb7u16.

We recommend that you upgrade your qemu-kvm packages.
