This update disables access to IMAP mailboxes through running imapd over rsh, and therefore ssh for users of the client application. Code which uses the library can still enable it with tcp_parameters() after making sure that the IMAP server name is sanitized. For Debian 8 "Jessie", this problem has been fixed in version 8:2007f~dfsg-4+deb8u1. We recommend that you upgrade your uw-imap packages.
