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 FreeBSD host is missing a security-related update.
Description
A number of issues relating to speculative execution were found last year and publicly announced January 3rd. Two of these, known as Meltdown and Spectre V2, are addressed here.
CVE-2017-5754 (Meltdown) - ------------------------
This issue relies on an affected CPU speculatively executing instructions beyond a faulting instruction. When this happens, changes to architectural state are not committed, but observable changes may be left in micro- architectural state (for example, cache). This may be used to infer privileged data.
CVE-2017-5715 (Spectre V2) - --------------------------
Spectre V2 uses branch target injection to speculatively execute kernel code at an address under the control of an attacker. Impact :
An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).
Solution
Update the affected package.
