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.

Synopsis
The remote Fedora host is missing a security update.
Description
Add new CPU features for CVE-2017-5715 and CVE-2018-3639 On Intel x86 hosts, the 'ssbd' feature must be explicitly added to any virtual machines that are not using host-passthrough/host-model CPU setup. NB this requires new microcode too, which is not yet available in Fedora microcode_ctl RPMs. On AMD x86 hosts, the 'virt-ssbd' feature must be explicitly added to any virtual machines that are not using host-passthrough/host-model CPU setup. There is no microcode dependency for AMD as this is a virtualized CPUID feature. In both cases, kernel >= 4.16.10-301 is required on the host and guest in order to activate the fix.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected 2:qemu package.
