Arch Linux Security Advisory ASA-201706-4
=========================================

Severity: High
Date    : 2017-06-05
CVE-ID  : CVE-2016-1037
Package : gajim
Type    : information disclosure
Remote  : Yes
Link    : https://security.archlinux.org/AVG-284

Summary
=======

The package gajim before version 0.16.8-1 is vulnerable to information
disclosure.

Resolution
==========

Upgrade to 0.16.8-1.

# pacman -Syu "gajim>=0.16.8-1"

The problem has been fixed upstream in version 0.16.8.

Workaround
==========

None.

Description
===========

Gajim through 0.16.7 unconditionally implements the "XEP-0146: Remote
Controlling Clients" extension. This can be abused by malicious XMPP
servers to, for example, extract plaintext from OTR encrypted sessions.

Impact
======

A malicious attacker can extract user session data by leveraging the
XEP-0146 (remote controlling clients) feature of the XMPP protocol,
which is enabled by default.
