Synopsis
========

Konversation contains multiple vulnerabilities that could lead to
remote command execution or information leaks.

Background
==========

Konversation is a user-friendly IRC client for KDE.

Affected packages
=================

    -------------------------------------------------------------------
     Package               /  Vulnerable  /                 Unaffected
    -------------------------------------------------------------------
  1  net-irc/konversation      < 0.15.1                      >= 0.15.1

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

Wouter Coekaerts has discovered three vulnerabilites within
Konversation:

* The Server::parseWildcards function, which is used by the "Quick
  Buttons", does not properly handle variable expansion
  (CAN-2005-0129).

* Perl scripts included with Konversation do not properly escape
  shell metacharacters (CAN-2005-0130).

* The 'Nick' and 'Password' fields in the Quick Connect dialog can be
  easily confused (CAN-2005-0131).

Impact
======

A malicious server could create specially-crafted channels, which would
exploit certain flaws in Konversation, potentially leading to the
execution of shell commands. A user could also unintentionally input
their password into the 'Nick' field in the Quick Connect dialog,
exposing his password to IRC users, and log files.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Konversation users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/konversation-0.15.1"
