181=head1 SECURITY CONSIDERATIONS
182
183CV uses Pixbuf to load images. Pixbuf is not considered safe for this
184purpose, though (from the gtk-2.2 release notes):
185
186"While efforts have been made to make gdk-pixbuf robust against invalid
187images, using gdk-pixbuf to load untrusted data is not recommended, due to
188the likelyhood that there are additional problems where an invalid image
189could cause gdk-pixbuf to crash or worse."

114=head1 BUGS/TODO 191=head1 BUGS/TODO
192
193 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
194 incompatible with utf-8 fails.
