Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution for Linux hosts on x86 hardware with x86 guests.

• CVE-2016-3710
  Wei Xiao and Qinghao Tang of 360.cn Inc discovered an out-of-bounds
  read and write flaw in the QEMU VGA module. A privileged guest user
  could use this flaw to execute arbitrary code on the host with the
  privileges of the hosting QEMU process.
• CVE-2016-3712
  Zuozhi Fzz of Alibaba Inc discovered potential integer overflow
  or out-of-bounds read access issues in the QEMU VGA module. A
  privileged guest user could use this flaw to mount a denial of

For Debian 7 Wheezy, these problems have been fixed in version
1.1.2+dfsg-6+deb7u13.

We recommend that you upgrade your qemu-kvm packages.
