SynopsisThe remote VMware ESXi host is missing one or more security-related patches.
DescriptionvCenter Server, ESXi, Workstation, and Fusion update speculative execution control mechanism for Virtual Machines (VMs). As a result, a patched Guest Operating System (GOS) can remediate the Speculative Store bypass issue (CVE-2018-3639) using the Speculative-Store- Bypass-Disable (SSBD) control bit. This issue may allow for information disclosure in applications and/or execution runtimes which rely on managed code security mechanisms. Based on current evaluations, we do not believe that CVE-2018-3639 could allow for VM to VM or Hypervisor to VM Information disclosure.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2018-3639 to this issue.
