Yes. Because a slave SERVER has authority to EXECUTE any statement read from a master's binary log, special security constraints exist for using stored functions with replication. If replication or binary logging in general (for the purpose of point-in-time recovery) is active, then MySQL DBAs have TWO security options open to them:

Any user wishing to create stored functions must be granted the SUPER privilege.

ALTERNATIVELY, a DBA can set the log_bin_trust_function_creators system variable to 1, which enables anyone with the standard CREATE ROUTINE privilege to create stored functions.
