Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of open-vm-tools installed on the remote host is prior to 12.2.5-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2139 advisory.

 A fully compromised ESXi host can force VMware Tools to fail to authenticate host-to-guest operations, impacting the confidentiality and integrity of the guest virtual machine. (CVE-2023-20867)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update open-vm-tools' to update your system.
