Official summary
Some 2015-2017 Mustang vehicles equipped with a 5.0L engine may exhibit an oil leak from either valve cover gasket. This may be due to the number of fasteners used to hold the valve cover onto the cylinder head. To correct the condition, follow the Service Procedure steps to add fasteners to both valve covers.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
