235=head1 SECURITY CONSIDERATIONS
236
237CV uses Pixbuf to load images. Pixbuf is not considered safe for this
238purpose, though (from the gtk-2.2 release notes):
239
240"While efforts have been made to make gdk-pixbuf robust against invalid
241images, using gdk-pixbuf to load untrusted data is not recommended, due to
242the likelyhood that there are additional problems where an invalid image
243could cause gdk-pixbuf to crash or worse."
130 244
131=head1 BUGS/TODO 245=head1 BUGS/TODO
246
247 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
248 incompatible with utf-8 fails.
