Clients older than 3.3.0 can no longer connect/synchronize. Users must upgrade.

using version 3.1.3 in TAILS ...upon opening the wallet it states there has been an error...and it won't let me report it automatically. The manual error is:

Traceback
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/electrum/util.py", line 794, in run_with_except_hook

Additional information
Electrum version: 3.1.3
Operating system: Linux-4.19.0-1-amd64-x86_64-with-debian-9.7
Wallet type: standard
Locale: en_US

The wallet simply will not synch or won't connect at all.

Please upgrade.This is fixed in 3.3

Clients older than 3.3 can no longer connect to the network. Users should go to electrum.org and download the latest version of Electrum.

We have found a DOS vulnerability in them where a server can send them certain invalid data that they cannot parse and this kills the client's network thread (all networking functionality). Old clients are vulnerable to phishing messages from servers via which users kept getting tricked and losing money. To put an end to this, we've deliberately started exploiting the DOS vulnerability to make old clients unusable, hence force users to update.

It is unfortunate that this also affects Tails users, where it's not exactly easy to update. Sorry about this.

I suggest that you download the AppImage and run that. This can also be done on Tails, and is easy.

For Linux in general, see FAQ

Can't upgrade because latest Electrum requires newer python version. It is really unfortunate that old versions were intentionally disabled.

SomberNight commented 5 years ago

@NiExTy see https://github.com/spesmilo/electrum-docs/blob/master/faq.rst#electrum-requires-recent-python-my-linux-distribution-does-not-yet-have-it-what-now

In particular, can you try using the AppImage?

NiExTy commented 5 years ago

Appimage requires 64-bit OS, so no. I will try to do 5. for now.

Applying this diff (which simply wraps the vulnerable code with a try..except block) to network.py (typically at /usr/local/lib/python3.5/dist-packages/electrum/network.py or a similar location) should fix the remote networking thread crash vulnerability in Electrum v3.1.3.

pontescm commented 5 years ago

i've downloaded the latest release of Electrum 3.3.6 at https://electrum.org/#download but when it doesnt connect anyway, neither selecting manual servers nor automatic option

SomberNight commented 5 years ago

@pontescm try a few different servers and also review debug logs. If you can't figure out the issue, or if there is something interesting in your debug logs, please open a new issue and include your logs.
