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.
