🤔🔒🐮 What's up? - LDAP Integration

Moohoo everyone!

As already announced on social media channels, today we are serving you a new edition of our section: What's up?.

Today, we are explicitly discussing a topic of burning interest to all of us: LDAP/OIDC Integration and the associated overhaul of the authentication system.

We have kept you updated in the past that we are feverishly working on integrating LDAP and OIDC. After all, this function is not without reason one of the most requested features for mailcow ever – and rightly so!

However, our plan was to release this whole thing in the first quarter of 2024 or maybe even around Christmas 2023. As you have noticed, both timelines could not be met…

🐥🐄 Febmooary 2024 Update | ClamAV Security Update

2024-02 (Release 15th February 2024)Moohoo Everyone! With Febmooary, further recently released security vulnerabilities in mailcow have been addressed. These are the following security vulnerabilities in the ClamAV service that were fixed with version 1.2.2: CVE-2024-20290: Fixed a possible heap overflow read bug in the OLE2 file parser that could cause a denial-of-service (DoS) condition. CVE-2024-20328: Fixed a possible command injection vulnerability in the “VirusEvent” feature of ClamAV’s ClamD service. In the default configuration, mailcow is not affected by the CVE-2024-20328 vulnerability, as the VirusEvent in the ClamAV configuration is not activated.

🔒🔑 External Identity Providers for User authentication

Moohoo - Good News, everyone! With the Nightly Branch, it is now possible to use an external Identity Provider as an additional authentication source. mailcow utilizes the OIDC (OpenID Connect) protocol to authenticate only mailbox users. To enable this, we have made some changes to the way authentication works. Let’s talk about what has changed, what we had in mind, and what we plan to add in the future. Of course, we will also show you how to use the new feature.
