Cross Object Field Update - Campaign Membership > Contact


I've need to get a Contact checkbox field =TRU when the same contact is a campaign member of a specific campaign. Can you please help me?

Thanks Rahul. I actually need the other way around. I need to record in the contact record when a contact is part of a specific campaign, and has a specific campaign memebr status, too.

I've found some info in another form eventually and here is what I used:
trigger updateContact on CampaignMember (before update){
  List<id> contactIds=new List<Id>();
    if(cm.ContactId != null){
      System.debug('Status is ' + cm.Status);
      if(cm.Status == 'Cancelled'){
        System.debug('Id is ' + cm.ContactId);
  List<Contact> contacts=[SELECT Id,    TestTrustee__c FROM Contact WHERE Id IN : contactIds];
  for(Contact c:contacts){
      System.debug('Found contact ' + c);
    update contacts;
  System.debug('Contacts to update list size ' + contacts.size());
  }catch (DMLException e){
    system.debug('contact update failed: '+e);
