237=head1 SECURITY CONSIDERATIONS
238
239CV uses Pixbuf to load images. Pixbuf is not considered safe for this
240purpose, though (from the gtk-2.2 release notes):
241
242"While efforts have been made to make gdk-pixbuf robust against invalid
243images, using gdk-pixbuf to load untrusted data is not recommended, due to
244the likelyhood that there are additional problems where an invalid image
245could cause gdk-pixbuf to crash or worse."
168 246
169=head1 BUGS/TODO 247=head1 BUGS/TODO
248
249 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
250 incompatible with utf-8 fails.
