Shibboleth 2.2.0 Available

Version 2.2.0 of our privacy and security aware mailing list manager has been released. This release includes a new feature: killing free mailer ads and addresses an important weakness in PGP signature generation.

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.

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.
