medium Nessus Plugin ID 192568

Language:

Synopsis

The remote VMware ESXi host is affected by multiple vulnerabilities.

Description

The version of VMware ESXi installed on the remote host is prior to 6.7 P07, or 7.x prior to 7.0 Update 3e. It is, therefore, affected by multiple vulnerabilities as referenced in the VMSA-2022-0016 advisory:

 - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21123)

 - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

 - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to VMware ESXi 6.7 P07, or 7.0 U3e or later.
