I should remember -- morning coffee first, then post.

The CA root certs themselves have not been cracked -- It is the digital
signatures created by some CAs who still use MD5 to sign the certs that
they issue that have been hacked: The known weakness in MD5 allows one
to create two certs with the same MD5 hash, one that is legitimate to
get signed by the CA, and another one for rogue use that can be given
the same signature.
