Description:
Luigi Auriemma has reported some vulnerabilities in Yager, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.
1) A boundary error in the handling of the nickname field can be exploited to cause a buffer overflow by sending some specially crafted data to a vulnerable server.
Successful exploitation can lead to execution of arbitrary code.
2) A boundary error in the communication handling can be exploited to cause a buffer overflow by sending an overly long data block to a vulnerable server (more than 256 bytes).
3) An error in the communication handling can be exploited to freeze a vulnerable server by sending an incomplete data block.
4) An error in the communication handling can be exploited to crash a vulnerable server via some malformed data.
The vulnerabilities have been reported in version 5.24 and prior. Other versions may also be affected.
