Description


Wouter Coekaerts has reported a vulnerability in Quassel IRC, which can be exploited by malicious people to hijack IRC connections.

The vulnerability is caused due to the application not properly handling quoted newline characters when processing CTCP requests. This can be exploited to inject newlines into the user's response, which can be used to e.g. execute IRC commands in the context of the user's IRC session.

The vulnerability is reported in versions prior to 0.3.0.3.


Solution:
Update to version 0.3.0.3.
