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 service (QEMU process crash).

For the stable distribution (jessie), these problems have been fixed in version 1:2.1+dfsg-12+deb8u6.

We recommend that you upgrade your qemu packages.");
