195=head1 SECURITY CONSIDERATIONS
196
197CV uses Pixbuf to load images. Pixbuf is not considered safe for this
198purpose, though (from the gtk-2.2 release notes):
199
200"While efforts have been made to make gdk-pixbuf robust against invalid
201images, using gdk-pixbuf to load untrusted data is not recommended, due to
202the likelyhood that there are additional problems where an invalid image
203could cause gdk-pixbuf to crash or worse."
56 204
57=head1 BUGS/TODO 205=head1 BUGS/TODO
206
207 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
208 incompatible with utf-8 fails.
