[Note: this post was updated on 15 July 2021 to correct the omission of two resolved issues, on 20 July to advise of potential hardware compatibility issues, and again on 29 July to update a CVE reference]

Email protection features in this release depend on CPU features introduced by Intel and AMD 10-15 years ago.

SG-series appliances and many older end-of-life Sophos appliance models are not affected. Devices running on KVM/QEMU or on hardware with older CPUs may experience issues - consult this article before upgrading.

Today we've released UTM 9.706. The release will be rolled out in phases.

  • In phase 1 you can download the update package from our download server.
  • In phase 2 we will make it available via our Up2Date servers in several stages.
  • In phase 3 we will make it available via our Up2Date servers to all remaining installations.

Up2Date Information

News

  • Maintenance Release
  • Strict TCP Session Handling enabled by default

    New installations of UTM 9.706 have strict TCP session handling enabled by default.
    When updating to 9.706 and strict TCP session handling is not enabled, admins can enable it under Network Protection > Firewall > Advanced.

  • Secure Up2Date

    Up2Date updates will be downloaded via HTTPS connections. In cases where UTM 9 is being used with an upstream proxy or behind a different firewall, it may be necessary to change the configuration on these devices to allow UTM 9 to retrieve Up2Date information via HTTPS.

  • Email Protection anti-spam engine changed to Sophos Anti-Spam Interface (SASI)

    Starting with this release, E-Mail Protection will use the Sophos Anti-Spam Interface (SASI) for anti-spam scanning. SASI is already being used as part of Sophos Email and will replace the currently used anti-spam engine in UTM 9.
    In case of false positive or false negative detections, please follow the instructions in this support article on how to submit a sample.

Remarks

  • System will be rebooted
  • Configuration will be upgraded
  • Connected REDs will perform firmware upgrade
  • Connected Wifi APs will perform firmware upgrade
