194=head1 SECURITY CONSIDERATIONS
195
196CV uses Pixbuf to load images. Pixbuf is not considered safe for this
197purpose, though (from the gtk-2.2 release notes):
198
199"While efforts have been made to make gdk-pixbuf robust against invalid
200images, using gdk-pixbuf to load untrusted data is not recommended, due to
201the likelyhood that there are additional problems where an invalid image
202could cause gdk-pixbuf to crash or worse."
120 203
121=head1 BUGS/TODO 204=head1 BUGS/TODO
205
206 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
207 incompatible with utf-8 fails.
