Issues Fixed in this Version

Security: Strongswan IKE Daemon for VPN Connections

In the source code of Strongswan, the IKE Daemon for VPN Connections a security hole has been discovered, which treated empty signatures as valid. This hole is going to be closed with a patch for the version

Web Proxy: Web Proxy does not start, Cache is deleted

When the proxy-cache has been emptied and reinitialized with the action “clear cache”, the directory structure could not be recreated in some cases. This resulted in the Web-Proxy-Service being unable to start. This will be fixed with this update.

VPN: UTF-8 Character within PSK String

Using special characters like € or @ in the preshared-key resulted in missing connection information in the gui under System → Monitoring/Analysis → Link Status and System → Monitoring/Analysis → IPsec. With this version the generation of the connection scripts has been improved in a way that UTF-8 characters are being used correctly. VPN status details are being shown correctly with this.

Authentication: Incorrect Calculation of the Primary Email Address when using ActiveDirectory and

the Collax AD-Proxy

The calculation of default mail addresses was broken for various reasons when user data was imported from ActiveDirectory via the Collax AD proxy. With this update a number of additional configuration variables are introduced to be used by the Collax AD proxy. This allows the calculation of the addresses to be performed correctly during runtime rather than configuration time.

Add-on Software: Files with suspicious extensions are filtered

Files with a suspicious extension (e.g. .jpg.exe) are filtered by the Avira scanner.

System Management: Logfiles when Checking LSI Controller Fills up Hard Disk

With this update the monitoring of LSI raid controller is going to be improved.
