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 is different from CVSS.

VPR Score: 5.9


The remote Fedora host is missing a security update.


Excessive checking in compatibility mode hypercall argument translation, Insufficient bounding of 'REP MOVS' to MMIO emulated inside the hypervisor, fix segfaults and failures in xl migrate
--debug Guest effectable page reference leak in MMU_MACHPHYS_UPDATE handling Insufficient restrictions on certain MMU update hypercalls, Missing privilege level checks in x86 emulation of far branches, Add fix for CVE-2014-0150 to qemu-dm, though it probably isn't exploitable from xen

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected xen package.
