VMware ESXi 6.5 / 6.7 / 7.0 Multiple Vulnerabilities (VMSA-2022-0020)

medium Nessus Plugin ID 192466

Synopsis

The remote VMware ESXi host is affected by multiple vulnerabilities.

Description

The remote VMware ESXi host is version 6.5, 6.7 or 7.0 and is affected by multiple vulnerabilities, as follows:

- Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29901)

- Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

- Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. (CVE-2022-23825)

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

Solution

Apply the appropriate patch or workaround as referenced in the vendor advisory.
