Description Andrej Nemec 2016-05-02 09:07:52 UTC 
It was found that quasselcore is vulnerable to a denial of service
attack by unauthenticated clients. The protocol negotiation did not
take into account lack of a match, in which case
PeerFactory::createPeer returns a nullptr, which is immediately
dereferenced.
