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.
VPR Score: 9.2
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionThe Xen Project reports :
Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations.
Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga' modes.
A privileged guest user could use CVE-2016-3710 to exceed the bank address window and write beyond the said memory area, potentially leading to arbitrary code execution with privileges of the Qemu process. If the system is not using stubdomains, this will be in domain 0.
A privileged guest user could use CVE-2016-3712 to cause potential integer overflow or OOB read access issues in Qemu, resulting in a DoS of the guest itself. More dangerous effect, such as data leakage or code execution, are not known but cannot be ruled out.
SolutionUpdate the affected package.
