Hi XG Community!

We’ve released SFOS v17.5.6 MR6 for the Sophos XG Firewall. Initially, the firmware will be available by manual download from your MySophos account. We then make the firmware available via auto-update to a number of customers, which will increase over time.

Please visit the following link for more information regarding the upgrade process: Sophos XG Firewall: How to upgrade the firmware.

Guidance on recently discovered security vulnerability in Exim email server

Exim is used by XG Firewall v17.5, specifically if a customer has enabled Email Protection. On Friday 7 June 2019, Sophos released and automatically applied an over the air hotfix to all XG Firewalls with auto-updates enabled to address this issue. If your XG Firewall does not have auto-updates enabled, upgrading to 17.5 MR6 release could resolve the issue. Alternatively, you can review KB134199.
