A vulnerability has been reported in UnrealIRCd, which can be exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the handling of the TKL command. This can be exploit to crash the service via a TKL command with specially-crafted arguments sent from another server.

Successful exploitation requires that the malicious server is allowed to connect via a server link.

The vulnerability has been reported in version 3.2.3. Prior versions may also be exploited.

Solution:
Update to version 3.2.4.
