9.604 without problems?

The Up2Date seemed to have hung 33 seconds in:

A few minutes later, I refreshed WinAdmin and, apparently it completed successfully.

sys-9.603-9.604-1.2.1.tgz (Jul 11 15:31)

I will post in this thread if I see anything else odd.

I just Up2Dated my lab and did not see the apparent hang.  Perhaps that's an issue with AWS instances.

No apparent problem with either UTM.

I had no problems updating the SG135 in my lab to version 9.604 and the UTM seems to work fine until now.

Kind regards, Holger

URGENT ALERT: Issue with RED 50 and 9.604 which fixes the TCP SACK PANIC vulnerability

I just received an SMS alert from Sophos: Up2Date to 9.604 after powering off your RED 50(s)! Otherwise, there's a good chance a RED 50 will be bricked.  Then after the before powering the RED 50 on again, execute the following commands as root at the command line:

cc set red use_unified_firmware 0
cc get red use_unified_firmware

If you're running in High Availability, I believe you must also execute these commands on the Slave - at least do the second one to confirm.  For that, you will need the loginuser and root passwords after doing the following as root at the command line:

ha_utils ssh

I just received the following from Sophos Support:

1. Are any other REDs in danger of being bricked, or is it just the RED 50?
- So far we have only seen RED 50 but this doesn't rule out RED 15
2. In High Availability, does use_unified_firmware need to be set to 0 on all nodes?
- No it would replicate the command
3. Instead of physically unplugging REDs, would it suffice to disable the RED server objects in WebAdmin before applying the Up2Date and then enable them after 9.604 has had use_unified_firmware set to 0?
- In theory yes if you disable the service in the UTM or turn off the RED devices, then they won't be able to get the Firmware Update, so they won't be able to contact the server, and once you re-enable the services they will not search for a new firmware update

hi

i had 2 dead  red 50's  back around the time we first upgraded to 9.6  , and had them replaced by sophos

i remember at the time setting this  unified firmware to  0 

currently running 9.603 and just checked the switch is set back to 1 

so are we saying that every new 9.6 update resets the switch to 1 ? 

so currently i have 9.603 with 2 red devices attached and everything is working , is there any comment from sophos , does it affect all red 50 devices , or only some revisions ? 

if they know this is a problem- and i think they have as this happened to us a few months ago , would it not make sense to set the firmware to 0 , in the update file ? or have the change persist after updates 

Hello

we have 2 Firewalls in HA. May I update both direct from Web Intrface? We have 6 RED 50 too outside.

May be Problems with the updates?

THX

Hello Peter,

You need to upload new updates to the master unit only in HA. The slave unit gets the updates pushed from the master.

By installing the update there is the risk that the setting "use_unified_firmware" is switched back to 1, with the mentioned problems above . Therefore it would be better to disable the RED50 for the update and check the settings afterward before enabling the RED50 again.

Kind regards, Holger

Hallo Peter and welcome to the UTM Community!

UPDATE 2019-07-31: See my latest post below.

First, read the threads above.  I'm getting ready to handle a similar situation with a client.  Here's a copy of the plan I proposed:

1. Disable the RED Servers in WebAdmin.
2. Start the Up2Date process and wait for it to complete - probably about 10 minutes or so.  Watch on the High Availability 'Status' tab for the new Slave to be READY.
3. At the command line, disable the use of unified wireless firmware.
4. Enable the RED Servers in WebAdmin.

The only disruption would be to an upload or download or VoIP call active at the moment the current Slave becomes the Master node.

9.605 has fixes apparently but according to the post in the below link  its all a bit convoluted ,  "disable the network behind the red before updating:......"
