VMware ESXi contains an arbitrary write vulnerability. A malicious actor with privileges within the VMX process may trigger an arbitrary kernel write leading to an escape of the sandbox.

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process.

VMware ESXi and Workstation contain a time-of-check time-of-use (TOCTOU) race condition vulnerability that leads to an out-of-bounds write. Successful exploitation enables an attacker with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host.

VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management https://blogs.vmware.com/vsphere/2012/09/joining-vsphere-hosts-to-active-directory.html by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.

A flaw was found in hw. Non-transparent sharing of branch predictor targets between contexts in some Intel(R) processors may potentially allow an authorized user to enable information disclosure via local access.

A flaw was found in hw. Incomplete cleanup in specific special register write operations for some Intel® Processors may allow an authenticated user to enable information disclosure via local access.

A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel® Processors may allow an authenticated user to enable information disclosure via local access.

A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel® Processors may allow an authenticated user to enable information disclosure via local access.

A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type, potentially leading to information disclosure.

VMware ESXi and vCenter Server contain a partial denial of service vulnerability in their respective authentication services. VMware has evaluated the severity of this issue to be in the Moderate severity range with a maximum CVSSv3 base score of 5.3.
