[Djigzo users] Is Ciphermail save against "Efail"?

by lst_hoe02＠kwsoft.de

Hello, today a new threat againts encrypted e-mail (PGP and S/MIME) is in the news: https://www.eff.org/deeplinks/2018/05/attention-pgp-users-new-vulnerabiliti… From what i understand the basic problem is that it is possible to inject special data in already encrypted e-mail, which than will be reported back after decryption with HTML URLs to the attacker and can be used to derive the key used for encryption. So i guess one would need the following conditions to be true for the attack to succeed - The MUA access external URLs to load content in HTML e-mail (automatically) - The e-mail will be decode despite the altered content (not vaild signed at least) - Probably many e-mails are needed to get the oracle attack to work? So for Ciphermail there should be no direct problem because it does not "read" the e-mail or obey URLs in the e-mail? But the question remains if there is a possibilty to prevent the "vulnerable" clients againts attack e-mail passing Ciphermail by not decrypting them or something like that? Maybe i'm totaly wrong, but thanks for any feedback on this Regards Andreas

[Djigzo users] New release of the CipherMail Email Encryption Gateway available (4.1.0-0)

by Martijn Brinkers

A new version of the CipherMail Email Encryption Gateway is available (4.1.0-0) Virtual Appliance downloads: https://www.ciphermail.com/downloads-virtual-appliance.html Distribution packages downloads: https://www.ciphermail.com/downloads-gateway-distributions.html Release notes: New * CertStore command line tool can now export certificates and keys * PGP commons line tool can now export public and secret keys * The back-end now supports a Mail attribute named remote-delivery.smtp.relay-host. It can be used to deliver email to a different relay host or local port based on content. * SetRecipients mailet added. This can be used to change the recipients of an email. * Post smime and pgp processor is now only called when a message was/is s/mime or PGP. This can be used to add specific behavior when a message is S/MIME or PGP (for example redirect to content scanner) * Systemd fetchmail.service unit file added. * Matcher added which can match on a user configurable list of senders/recipients. This also works for Exchange journaling messages by looking inside the journal [PRO/ENT]. * Intellicard Certificate Request handler added [PRO/ENT]. * Export database to XML [PRO/ENT]. Bugs/Improvements/Changes * Cipher suites for HTTPClient are no longer set. The Cipher suites config resulted in a bug after a Java update. The Java bug was only triggered in old versions of CipherMail that used a link to sunjce_provider.jar in /usr/share/djigzo/james-2.3.1/lib. * SleepTimeOnError added to SMSGatewayImpl background thread. The thread will sleep for 30 sec (default) if there was an exception in the background thread not caused by a transport. This is done to prevent filling up the logs if there is a problem with the database. * SMIME command line tool refactored. Now uses long option names. * System property ciphermail.crypto.cms.mustProduceEncodableUnwrappedKey added. This sets the mustProduceEncodableUnwrappedKey BC property. This is needed for supporting Utimaco HSMs. * MySQL/MariaDB SQL config minor change. varchar columns with size 128 increased to 255.The alias field was too short to fit a sha512 thumbprint and some prefix used by a cert request handler This resulted in an field too small error when trying to set the key alias (this was only an issue with the prof/ent. edition) * Postgres 10 does not allow the JDBC URL to end with /. The last / has been removed from the URL. * Postgres JDB driver updated to support Postgres 10. * Most required/depends removed from RPM and DEB conf files. It is impossible to support different RH/CentOS, Ubuntu. releases with one RPM or DEB because packages are renamed/removed. * The back-end front-end SOAP layer now uses Basic Authentication mode instead of WS security to work around a recently introduced Java bug in Java 1.8.0_162. (https://bugs.openjdk.java.net/browse/JDK-8196491, https://github.com/javaee/metro-jax-ws/issues/1209) * The CipherMail Virtual Appliance is now using CentOS 7 instead of Ubuntu and uses MariaDB instead of Postgres. This means that back-ups of previous CipherMail Virtual Appliance cannot be directly imported because the database type is changed. Users with a support contract can contact Us for help with migrating the database to the new version. Note: this only impacts users using the Virtual Appliance who wish to upgrade to the new CentOS based Virtual Appliance. * HSM module now supports RSAES-OAEP encryption scheme (requirement for the German edi@energy standard) [PRO/ENT]. * License check only checked if license was valid at startup [PRO/ENT]. * Selected Certificate Request Handler is now session persistent so the selection is remembered while session is active. * Jetty upgraded to release 9.4. This requires java 8 or up [PRO/ENT]. Upgrade guide can be downloaded from: http://www.ciphermail.com/documents/upgrade-guide.pdf Kind regards, Martijn Brinkers -- CipherMail email encryption Email encryption with support for S/MIME, OpenPGP, PDF encryption and secure webmail pull. https://www.ciphermail.com Twitter: http://twitter.com/CipherMail

by gulchi

Hi Martijn, hi list, thank you for your help in advance. I use Ciphermails internal CA for creating SMIME certificates. Now I download the CRLs manually from Ciphermails Web Interface. Is there a way to create and download the crl with the command line tool? Thank you very much. Best regards. Christian
