VMware Fusion CVE-2017-5753 Information Disclosure Vulnerability

Description

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. ) ESXi, Workstation and Fusion are vulnerable to Bounds Check Bypass and Branch Target Injection issues resulting from this vulnerability. Result of exploitation may allow for information disclosure from one Virtual Machine to another Virtual Machine that is running on the same host. The remediation listed in the table below is for the known variants of the Bounds Check Bypass and Branch Target Injection issues.
