1. Systems affected:

All Konversation versions up to and including 0.15

2. Overview:

Multiple vulnerabilities have been discovered in Konversation, an IRC client for KDE.

A flaw in the expansion of %-escaped variables makes that %-escaped variables in certain input strings will be inadvertently expanded too. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0129 to this issue.

Several perl scripts included with Konversation fail to properly handle command line arguments causing a command line injection vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0130 to this issue.

Nick and password are confused in the quick connection dialog, so connecting with that dialog and filling in a password, would use that password as nick, and may inadvertently expose the password to others. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0131 to this issue.


3. Impact:

A user might be tricked to join a channel with a specially crafted channel name containing shell commands. If user runs a script in that channel it will result in an arbitrary command execution.

If quick connect is used with a password, the password is used as nickname instead. As a result the password may be exposed to others.

4. Solution:

Upgrade to Konversation 0.15.1 available from
