Version 2.2.0 of Shibboleth, the privacy and security aware mailing list manager, is now available.
This release of Shibboleth addresses a weakness in the digital signature implementation that would make it possible for a malicious attacker to change the context of a message or the sender's identity from one Shibboleth user to another of the same list family. Also included is a new feature for killing the annoying free mailer advertisements.
Shibboleth is distributed under the terms of the GNU Lesser General Public License (LGPL) from SourceForge.
Support for Shibboleth provided on a best-effort basis of the developers is available by email and SourceForge public fora. Commercial support is available from Interhack Services, Inc., a subsidiary of Interhack Corporation.
