Beschreibung:	Summary: 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. Affected Software/OS: qemu on Debian Linux Solution: For the stable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6a+deb7u5. For the unstable distribution (sid), these problems have been fixed in version 2.1+dfsg-7. We recommend that you upgrade your qemu packages. CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
