236=head1 SECURITY CONSIDERATIONS
237
238CV uses Pixbuf to load images. Pixbuf is not considered safe for this
239purpose, though (from the gtk-2.2 release notes):
240
241"While efforts have been made to make gdk-pixbuf robust against invalid
242images, using gdk-pixbuf to load untrusted data is not recommended, due to
243the likelyhood that there are additional problems where an invalid image
244could cause gdk-pixbuf to crash or worse."
148 245
149=head1 BUGS/TODO 246=head1 BUGS/TODO
247
248 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
249 incompatible with utf-8 fails.
