Description:
Luigi Auriemma has discovered some vulnerabilities and a weakness in TinTin++ and WinTin++, which can be exploited by malicious people to cause a DoS (Denial of Service), manipulate data, or to compromise a user's system.
1) A boundary error exists within the "add_line_buffer()" function, which can be exploited to cause a stack-based buffer overflow via a specially crafted chat message.
Successful exploitation allows execution of arbitrary code.
2) The problem is that files that are received from remote clients are created insecurely without user interaction. This can be exploited to overwrite arbitrary files in the user's home directory with an empty file.
3) A null-pointer dereference error can be exploited to crash the client via a specially crafted chat message.
Successful exploitation of all vulnerabilities require that the client has initialised the chat functionality.
The vulnerabilities and weakness are confirmed in TinTin++ 1.97.9 and also reported in WinTin++ 1.97.9. Other versions may also be affected.
