Authenticated user have access to all social media profiles

I am a Drupal newbie so I may just have misconfigured things but it seems all authenticated users have access to all social media profiles when the "Administer own profiles" permission is assigned to the "authenticated user" role. I guess that is not the expected behavior.

To verify make sure the "Administer own profiles" permission is assigned to the "Authenticated User" role and access the social media profile of another authenticated user.

To fix this for my installation I made some changes to 'socialmedia.module'. In particular I made the following change to 'function socialmedia_menu()':

I replaced:

  'access arguments' => array('administer own profiles'),

with

  'access callback' => 'socialmedia_user_profile_access',
  'access arguments' => array(1, 'administer own profiles'),

and added the function 'socialmedia_user_profile_access'

  function socialmedia_user_profile_access($account, $access_type) {
    global $user;
    return user_access($access_type) && ($account->uid == $user->uid);
  }

Don't know if this is the right way to do this but at least it seems to work... ;-)
