How to check if a uploaded file is a pdf in Symfony 2

I'm working on the validation of one of my form and I need to check that the uploaded file is a pdf. I tried using a File constraint in my form, but it still let's me pass something that's not a pdf (a .txt for exemple).

Am I doing it wrong or should a use an other method to do that?

My form:

<?php

namespace AdminBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Validator\Constraints\File;

Class FormUpdateCV extends AbstractType
{
    public function buildForm(FormBuilderInterface $constructeur, array $options)
    {
        $format_fichier=new File(array(
                                'mimeTypes'=>'application/pdf',
                                'mimeTypesMessage'=>'Le fichier doit être un pdf'
                            ));

        $constructeur
        ->add('CV','file',array('label'=>'C.V.:', 'constraints'=>array($format_fichier)))
        ->add('mettreAJour','submit',array('label'=>'Mettre à jour'));
    }

    public function getName()
    {

        return 'update_CV';

    }
}

After trying some stuff, it seems like my previous condition does work. It's just that if I had, for exemple, a .pdf file and choose to change the extension to .txt, it still recognize it as a .pdf, but it still change the extention in my controller, so it's o.k. On the other side, if I change a .txt for a .pdf it still recognize the file as .txt, which is good since the file would read wright anyway.

You can add constraint directly in the entity. What do you think about this solution. 

// src/Acme/BlogBundle/Entity/Author.php
namespace Acme\BlogBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    /**
     * @Assert\File(
     *     maxSize = "1024k",
     *     mimeTypes = {"application/pdf", "application/x-pdf"},
     *     mimeTypesMessage = "Please upload a valid PDF"
     * )
     */
    protected $bioFile;
}
