Mandatory encryption on XMPP starts today

by The Prosody Team.

Last year Peter Saint-Andre laid out a plan for strengthening the security of the XMPP network. The manifesto, to date signed by over 70 XMPP service operators and software developers, offered a rallying point for those interested in ensuring the security of XMPP for its users. Today is the date that the manifesto gave for the final ‘flip of the switch’: as of today many XMPP services will begin refusing unencrypted connections.

by The Prosody Team.

We’re pleased to present Prosody 0.9.4, the latest release from our stable 0.9 branch. This release fixes a security (denial of service) issue.

Prosody 0.9.2 released

by The Prosody Team. Tags: release .

We are pleased to announce Prosody 0.9.2, the latest release of our stable 0.9 branch. The main focus of this release is on a couple of security improvements. A summary of changes in this release: Debian/Ubuntu packages fixed to always generate per-system certs (see below) TLS: Improved cipher string, and use Prosody’s preferred ciphers (see below) MUC: Fix for Spark clients not displaying room lists Packaged certificates It has always been our policy that Prosody should be secure out of the box, which is why we generate self-signed certificates for “localhost” at installation time, making it easy to get a simple XMPP server up and running in a couple of minutes.

Prosody 0.9.1 released

by The Prosody Team. Tags: release .

It’s been a great couple of weeks since Prosody 0.9.0 was released, but we’ve fixed a small number of issues and are happy to present our 0.9.1 release. A summary of changes in this release: Config: Fix the workaround for LuaSec 0.4.x to apply the ssl ‘ciphers’ option correctly Config: Ability to specify the ssl ‘dhparam’ option simply as a path to a file, instead of a callback function Windows: Fix s2s issues Windows: Fix the ability to specify absolute paths to SSL certificates in the config Build: Fix compilation issue on non-Linux systems that have glibc (such as Debian GNU/kFreeBSD) API: Fix to our set library, that caused the :include() and :exclude() methods to behave incorrectly Download instructions for many platforms can be found on our download page

Prosody 0.9.0 released

by The Prosody Team. Tags: release .

Yes! Prosody 0.9.0 is here! Over 1500 commits have been made by twelve people since 0.8, and even more have gone into third-party libraries that we have been contributing to such as LuaSocket, LuaSec and LuaEvent. IPv6 Our first big feature to announce is IPv6 support throughout. After releasing 0.8, this was by far our most voted-for issue in our tracker. Many thanks especially go to Florian Zeitz who worked on the bulk of IPv6 support in both Prosody and LuaSocket.

It is strongly recommended that all 0.9 users upgrade - these issues affect all versions of 0.9 since we released beta1 (~nightly build 119). Prosody 0.8 is not affected. Summary of changes: [major] Fixed a segfault in our SCRAM authentication code that can allow unauthenticated users to crash a Prosody instance.

Prosody 0.9.0rc4 available for testing

by The Prosody Team. Tags: release .

We decided there wasn’t enough suspense about the 0.9.0 release yet, so we’ve decided to issue another release candidate to keep you on your toes. In fact, some of the changes we made for rc3 to keep compatible with the new LuaSocket 3.0 didn’t compile on some platforms. This should now be fixed. We also realised that although we have set a number of new defaults for our TLS configuration (see previous release notes), we had not set a list of acceptable ciphers, which led some clients and servers to negotiate ciphers that might be considered weak.
