Bug Description

SRU REQUEST:

[Impact]

Xchat-Gnome (and xchat) for the use of SSLv3. Since the Poodle attack on SSLv3, many servers are now disabling the use of SSLv3, making xchat-gnome unsable to connect successfully.

[Test Case]

Install xchat-gnome and connect to an irc server that no longer offers SSLv3.

[Regression Potential]

This update may possibly introduce compatibility issues with sites that don't properly handle TLSv1.2 negotiations. While such sites existed in the past, they aren't likely to be common at the present time. Unfortunately, there is no ultimate solution that would be compatible with both scenarios.

Original report:

slack.com is a chat service with optional IRC integration. Since today I can no longer connect to their IRC gateway using XChat-GNOME. The error is:

> * Nepavyko prisijungti. Klaida: (336130315) error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
> Ar tai tikrai SSL šifravimą palaikantis serveris ir prievadas?

which, translated from lt_LT, means

> * Cannot connect. Error: (336130315) error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
> Does the server/port really support SSL?

I think this is part of the fallout of CVE-2014-3566 (aka POODLE). XChat-GNOME is trying to use the insecure SSL protocol version 3, and Slack, reasonably enough, rejects that.

Hi mgedmin,

Could you please test the fixed package I've uploaded to my testing PPA here:

https://launchpad.net/~mdeslaur/+archive/ubuntu/testing

If that works for you to connect to irc.slack.com, I'll work on preparing an SRU.

Thanks!
