Security

This update of VMware Fusion exposes hardware support for branch target injection mitigation to VMware guests.   This hardware is used by some guest operating systems to mitigate CVE-2018-5715 (also called by the name "Spectre").

For a guest operating system to use hardware support for branch target injection mitigation, the following steps must be taken:

1. Install this update of VMware Fusion
2. Ensure that your VM is using Hardware Version 9 or higher.  For best performance, Hardware Version 11 or higher is recommended.
3. Update your guest operating system with fixes for CVE-2018-5715 (consult the operating system vendor for these updates).
4. Update the host firmware (or CPU microcode, if host firmware cannot be updated).

Please see VMware knowledge base article 52085 for more details.
