xchat-gnome vulnerability
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

XChat-GNOME could be made to expose sensitive information over the network.

Software Description:
- xchat-gnome: simple and featureful IRC client for GNOME

Details:

It was discovered that XChat-GNOME incorrectly verified the hostname in an
SSL certificate. An attacker could trick XChat-GNOME into trusting a rogue
server's certificate, which was signed by a trusted certificate authority,
to perform a man-in-the-middle attack.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
  xchat-gnome                     1:0.30.0~git20141005.816798-0ubuntu6.2

Ubuntu 14.04 LTS:
  xchat-gnome
1:0.30.0~git20131003.d20b8d+really20110821-0.2ubuntu12.2

Ubuntu 12.04 LTS:
  xchat-gnome                     1:0.30.0~git20110821.e2a400-0.2ubuntu4.3

After a standard system update you need to restart XChat-GNOME to make
all the necessary changes.
