Description:
Several vulnerabilities were reported in the KDE Konversation software. A remote user may be able to cause a target user to execute arbitrary commands. A target user may disclose their password to other users.
Wouter Coekaerts reported that the software does not properly expand %-escaped variables in certain input strings due to a flaw in the 'Server::parseWildcards' function [CVE: CAN-2005-0129]. A remote user may be able to cause a target user to execute shell commands.
Some Konversation perl scripts do not properly validate command line inputs, such as the $SERVER or $TARGET parameters [CVE: CAN-2005-0130]. A remote user may be able to get a target user to join a specially named channel. Then, if the target user runs a script in that channel, arbitrary shell commands may be executed on the target user's system.
The nick and password parameters are confused in the quick connection dialog, so a target user connecting with that dialog may expose their password [CVE: CAN-2005-0131].
The vendor was notified on January 18, 2005.

Impact:
A remote user may be able to cause a target user to execute arbitrary commands when the target user takes certain actions.
A target user may disclose their password to remote users.
|
Solution:
Gentoo has released a fix and indicates that all Konversation users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/konversation-0.15.1"

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"
