- Security vulnerability fixes.
-
- * mail-display.c (do_external_viewer): Make sure that we don't
- launch a bonobo control to view a mime-type that we handle
- internally, otherwise maliciously formed HTML mail using <object>
- tags could potentially launch a bonobo vontrol to view the mime
- part bypassing any checks that Evolution might do on the data
- normally.
-
- * mail-format.c (handle_text_html, attachment_header)
- (handle_image, handle_via_bonobo): Encode the result from
- get_cid() so that malicious Content-Id strings cannot bypass the
- user's preference to not load http images, force a bonobo control
- to load passing it arbitrary data, etc.

-
* mail-signature-editor.c (menu_file_save_cb): Rewritten to do the
same as the composer's build_message() code.
