New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities were discovered in qemu-kvm, a full virtualization solution on x86 hardware.
- 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.
SolutionUpgrade the qemu-kvm packages.
For the stable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6+deb7u5.
