172=head1 SECURITY CONSIDERATIONS
173
174CV uses Pixbuf to load images. Pixbuf is not considered safe for this
175purpose, though (from the gtk-2.2 release notes):
176
177"While efforts have been made to make gdk-pixbuf robust against invalid
178images, using gdk-pixbuf to load untrusted data is not recommended, due to
179the likelyhood that there are additional problems where an invalid image
180could cause gdk-pixbuf to crash or worse."
56 181
57=head1 BUGS/TODO 182=head1 BUGS/TODO
183
184 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
185 incompatible with utf-8 fails.
