Synopsis:    VMware Virtual Appliance updates address side-channel
             analysis due to speculative execution
Issue date:  2018-02-08

1. Summary

   VMware Virtual Appliance updates address side-channel analysis due
   to speculative execution

   Note:

   This document will focus on VMware Virtual Appliances which are
   affected by the known variants of CVE-2017-5753, CVE-2017-5715, and
   CVE-2017-5754. For more information please see Knowledge Base article 
   52264.
   
   These mitigations are part of the Operating System-Specific
   Mitigations category described in VMware Knowledge Base article
   52245.

2. Relevant Products

   vCloud Usage Meter (UM)
   Identity Manager (vIDM)
   vCenter Server (vCSA)
   vSphere Data Protection (VDP)
   vSphere Integrated Containers (VIC)
   vRealize Automation (vRA)

3. Problem Description

   VMware Virtual Appliance Mitigations for Bounds-Check bypass, Branch
   Target Injection, and Rogue data cache load issues

   CPU data cache timing can be abused to efficiently leak information
   out of mis-speculated CPU execution, leading to (at worst) arbitrary
   virtual memory read vulnerabilities across local security boundaries
   in various contexts. (Speculative execution is an automatic and
   inherent CPU performance optimization used in all modern processors.)
   Successful exploitation may allow for information disclosure.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has
   assigned the identifiers CVE-2017-5753 (Bounds Check bypass),
   CVE-2017-5715 (Branch Target Injection), CVE-2017-5754 (Rogue data
   cache load) to these issues.

   Column 5 of the following table lists the action required to
   mitigate the observed vulnerability in each release, if a solution
   is available.
