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.
