That's the main thing. If you allow the user to e.g. provide names for maps, such names should be limited to alphanumeric characters and limited to a reasonable length. If you allow the user to provide a list of inputs, limit both the maximum number of items and the total length of the resulting textual representation. And so on. In short, GRASS modules are designed for use by local users who already have shell access, so there hasn't been any need to program defensively. The OS prevents people from e.g. reading or writing files which they aren't supposed to. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
