RichBaldry Is Sophos aware of and working on this?
Under 58906, 58907 on the ID.

Thanks for the info! Unfortunately the Snort site doesn't have details on the two IDs. I'm afraid that the Snort software itself needs to be updated by/on Sophos though. I currently see Snort Version 220.127.116.11 on a 9.710-1 Sophos UTM. I found this interesting link which states that the Snort engine can be delivered by Sophos via the pattern updates. That's why I tried to ask RichBaldry here.
