Thanks to the fact that peers establish connections (by default) to eight other peers, if a provided neighbor denies the existence of a specific resource, the peer can learn it from his other neighbors. Bitcoin is sustained by an equilibrium of financial incentives. Depending on the application, this could possibly not be an issue or even might not be considered a safety challenge. Furthermore, if a neighbor says he has some resource he actually does not have, peers will notice when they attempt to retrieve it (considering the fact that transactions and blocks are identified by their hash).
