Windows 7

Problem exists in 2.75a c27589e

If I use a texture and want the texture to appear only once on my object (no repeat), I use the min/max properties of the mapping node. Using this, the texture appears only one time but the border of the image gets stretched all over the rest of my object.

Your setup wouldn't give you expected for you result, it's actually implementation of border extension method, when pixels from image border are repeated for mapping coordinates outside of 0..1 range.

What you need to do instead is to use latest testbuild form http:*download.blender.org/release/Blender2.76/ or latest nightly build from builder.blender.org, set image extension to Clip and disable Min/Max clipping in the mapping node. For more details you can consult https:*blender.org/manual/render/cycles/nodes/textures.html#image-texture

So thanks for the report, but it's not a bug.
