qemu-kvm - security update

Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution on x86 hardware.

• CVE-2015-5165
  Donghai Zhu discovered that the QEMU model of the RTL8139 network
  card did not sufficiently validate inputs in the C+ mode offload
  emulation, allowing a malicious guest to read uninitialized memory
  from the QEMU process’s heap.
• CVE-2015-5745
  A buffer overflow vulnerability was discovered in the way QEMU
  handles the virtio-serial device. A malicious guest could use this
  flaw to mount a denial of service (QEMU process crash).

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.1.2+dfsg-6+deb7u9.

We recommend that you upgrade your qemu-kvm packages.
