Security fixes in several components

The update fixes less critical security vulnerabilities in the Linux kernel, the Avira virus scanner, multiple system libraries and tools.

Tagging of all inbound mails

It used to be possible to tag the subject of inbound mails only if a local email address was used as sender. Now an additional option allows you to tag the subject of each inbound mail with a userdefined prefix instead.

Reset of network card driver on new thin servers

Under hight network load, network driver resets occured on recently bought thin servers, leading to short interruptions of the network communication. With the previous update the problem had been fixed for the newest device generation. This update will enable the fix also for devices with a slightly older mainboard revision.

Minor bugfixes and improvements

Blocking of URLs and headers in reverse proxy

It is now possible to block requests with certain URLs or headers for all configured ports. This can help to prevent the exploitation of security vulnerabilities in the web applications of background servers until a bugfix becomes available.

Hyper-V: sequence of network cards mixed up

Since update 7.1-4.0 it could happen that after a reboot the sequence of network cards was wrong. Only virtual systems running in a Hyper-V host are affected.

Mail client with OAuth2 authentication for Microsoft 365

Mandatory header for mail archive

A new option in the mail archive settings lets you configure a header which must be present in a mail to be stored. You can use this e.g. to store mails only if they have been sent by the journal feature of your Exchange Online tenant.

IPsec interface on bridge

Since 7.1-4.0 data received via IPsec was discarded if the ipsec interface is linked to a bridge.

Minor bugfixes and improvements

F-Secure antivirus app

On some devices the mail virusscan failed after a reboot.
The web proxy content filter displayed a wrong message for password protected or encrypted files (virusscanner not installed)

URL filter database category "Spyware"

In version 7.1-4.0 we integrated a new datasource for the "Spyware" category into the free URL filter database. Unfortunately this datasource defines the term spyware very broadly, resulting in problems with some web sites. We significantly reduced the number of entries taken from this datasource.

Domainlists and IP lists

The following additions have been made:
  • OFFICE: cdn.office.net
  • WINDOWS: update servers for Exchange Antimalware
  • ANTIVIRUS: update server for Sophos virus scanners
The new IP lists GOOGLE_CLOUD and MICROSOFT_AZURE have been added as IP objects. The IP list AMAZON has been renamed to AMAZON_AWS.
