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.or=
g)
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,=20
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.

http://download.berlios.de/konversat...0.15.1.tar.bz2
