These questions can easily be answered, by running this simple query: "Get OpenSSL versions."
On the **Queries** page, enter the query name, "Detect Linux hosts with high severity vulnerable versions of OpenSSL," in the search box, select the query from the results table, and navigate to the **Edit or run query** page.
On the **Queries** page, enter the query name, "Get OpenSSL versions," in the search box, and select it to enter the **query console**. Then from the **query console**, hit "Run query", and from the "Select targets" page, select "All hosts," to run this query against all hosts enrolled in your Fleet. Then hit the "Run" button to execute the query.
