Summary: 

A Citrix XenServer potential vulnerability has recently been reported that could pose a security risk to any system using XenServer Hypervisor, including the Intel® Hybrid Cloud (IHC) platform which uses Citrix XenServer VMM as the virtualization platform.  While we are not aware of any active exploitation of this issue, Intel is releasing updated versions of the Intel® Hybrid Cloud software to mitigate the potential vulnerability.

Description: 

Some 64-bit operating systems and virtualization software running on Intel CPU hardware are potentially vulnerable to a local privilege escalation attack.  Intel’s processors are functioning within specification; this is a software implementation issue. The potential vulnerability may be exploited for local privilege escalation or a guest-to-host virtual machine escape. Citrix Xen has released hotfixes for this software implementation vulnerability and Intel has incorporated those mitigations into the Intel® Hybrid Cloud software versions shown in the chart below.
