As stated in the Google Webmaster Guidelines, they would only penalise your website if you had malicious duplicate content (e.g., many pages filled with scraped content).

https://support.google.com/webmasters/answer/2721312Duplicate content on a site is not grounds for action on that site unless it appears that the intent of the duplicate content is to be deceptive and manipulate search engine results. If your site suffers from duplicate content issues, and you don't follow the advice listed above, we do a good job of choosing a version of the content to show in our search results.
