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.
