Bounds-Check bypass and Branch Target Injection 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).

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

For more information on the vulnerabilities, see VMware Response to Speculative Execution security issues, CVE-2017-5753, CVE-2017-5715, CVE-2017-5754 (aka Spectre and Meltdown) (52245) .
