Description of problem: curl's upstream test-suite is paralyzed by the update of stunnel to 5.34 because of unnecessary change in its default behavior. The requireCert option should default to no. This cannot be easily worked around in upstream curl because the requireCert option does not exist in older versions of stunnel. Version-Release number of selected component (if applicable): stunnel-5.34-1.fc25 Additional info: Already fixed upstream. Please consider updating to 5.35 (bug #1187930).
