Security vulnerability fixes.
2003-03-12 Jeffrey Stedfast <fejj@ximian.com> Security vulnerability fixes. * 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. svn path=/trunk/; revision=20268
