Civil Liberties are laws that every* person has and in fact cannot be taken away by any other person or institutions. Which is including the Government. Civil Liberties are always in legal texts. For example, the Constitution and it's amendments that it has. In that case when you are in the United States and in a lot of other countries or even in treaties. In example the "European Convention on Human Rights." In fact Civil Liberties are way different from Privilege's. A example for Civil Liberties is "Freedom of Speech." A example of "Privilege" is the right to draft a will.
*It is depending on the context and the country in fact. Civil Liberties in fact can hold for all people in the world or it can also be for the people in a certain country.
