Several vulnerabilities were discovered in qemu, a fast processor emulator.
CVE-2014-3689 The Advanced Threat Research team at Intel Security reported that guest provided parameter were insufficiently validated in rectangle functions in the vmware-vga driver. A privileged guest user could use this flaw to write into qemu address space on the host, potentially escalating their privileges to those of the qemu host process.
CVE-2014-7815 James Spadaro of Cisco reported insufficiently sanitized bits_per_pixel from the client in the QEMU VNC display driver. An attacker having access to the guest’s VNC console could use this flaw to crash the guest.
