bannedit has reported a vulnerability in BitchX, which can potentially be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when handling IRC MODE messages. This can be exploited to cause a buffer overflow by sending a MODE message with an overly long parameter to an affected IRC client.
Successful exploitation may allow the execution of arbitrary code, but requires that the user is tricked into connecting to a malicious server.
The vulnerability is reported in BitchX 1.1. Other versions may also be affected.
Solution: Do not connect to untrusted IRC servers.
