Informational messages from the virtual machine to the VMX file must be limited on the virtual machine (VM).
An XCCDF Rule
Description
<VulnDiscussion>The configuration file containing these name-value pairs is limited to a size of 1MB. If not limited, VMware tools in the guest operating system are capable of sending a large and continuous data stream to the host. This 1MB capacity should be sufficient for most cases, but this value can change if necessary. The value can be increased if large amounts of custom information are being stored in the configuration file. The default limit is 1MB.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
