As we noted earlier on Oct 16, Nov 24 and Dec 4, VMware has introduced new TPS (Transparent Page Sharing) management options. Today’s release of ESXi 5.5 U2d restricts TPS to individual VMs and disables inter-VM TPS by default unless an administrator chooses to re-enable it. Please see KB 2097593 for full details on the functionality.
Additionally VMware has today released the following new and updated advisories:
The new advisory details a privilege escalation (CVE-2014-8370), denial of service issues (CVE-2015-1043, CVE-2015-1044) in Workstation, Fusion and ESXi and updates to third-party libraries in VMware vSphere.
Customers should review the security advisory and direct any questions to VMware Support.
