The security fix to map_yp_alias in 1.4.18 turned out to be incomplete. We also experienced some regressions in the updated filter plugin. Both are addressed in this new release 1.4.19 which contains a few other small fixes aswell. If you do not use map_yp_alias or the filters plugin there's no urgent need to upgrade now if you already installed 1.4.18.
