I don't think you can update this yourself. I opened bing maps and it says 2013 Microsoft corporation. 2012 Nokia in the lower right hand corner of the app.
I don't think the map data is locally stored, it pulls from the internet. If something is outdated, I recommend checking with Microsoft first.
