Description:
A vulnerability has been reported in Unichat, which can be exploited by malicious users to crash other user's clients.
The vulnerability is caused due to an error when handling characters. This can be exploited by adding additional characters to the file "u2res000.rit", which will crash other user's clients when a chatroom is visited.
It is also possible for malicious users to manipulate room names because the "Only ops set topic" option isn't set. This can eg. be exploited by logging on a UniChat server with a mIRC client.
Reportedly, other unspecified issues are also present.
Solution:
Use another product.
