[SECURITY] [DLA 653-1] qemu-kvm security update

Package : qemu-kvm
Version : 1.1.2+dfsg-6+deb7u16
CVE ID : CVE-2016-7161 CVE-2016-7170 CVE-2016-7908

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.
