The warning is generated by yum, saying that its own database of installed 
packages does not match the rpm database. This basically means that sometime 
back you have used rpm directly to install/remove some package, circumventing 
yum. You are not supposed to install rpm packages behind yum's back. :-)

The warning has nothing to do with the vsftpd package which is being updated 
in this instance. It's rather yum performing the database check when the 
transaction starts.

HTH, :-)
