Electrolyte usually leaks out through the capacitor's top vents (which your capacitors don't have) or its leads, and dries to a light colored powder. This article explores the causes, symptoms, and how to measure and fix a leaking capacitor It also provides advice on low leakage capacitors and capacitor replacement. The glue only corrodes the legs of the capacitor and doesn't impact upon the internals of the capacitor I thought it was the dried remains of a leak at first but some googling indicates that it might just be glue as capacitors were often supported with a glob of adhesive. If you suspect a leaky capacitor in your device, unplug it immediately and avoid using it until the capacitor can be replaced
What often appears as white stuff leaking from electronic capacitors is typically not a harmful leak at all, but rather a type of adhesive used during the manufacturing process This substance is applied deliberately to secure components and is a normal part of their construction. Looks like glue to me because the area covered by the caps' bodies is clean, and if the cap oozed goo, that area would certainly show some, since leakage is likely to occur around the caps' leads first.
