Description


Luigi Auriemma has reported some vulnerabilities in Georgia SoftWorks SSH2 Server, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

1) A format string error in the log function when handling usernames can be exploited by sending a username containing format string specifiers.

2) A boundary error in the log function when handling usernames can be exploited to cause a buffer overflow by sending an overly-long username.

3) A boundary error within the handling of passwords can be exploited to cause a buffer overflow by sending an overly-long password.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are reported in version 7.01.0003. Other versions may also be affected.


Solution:
Restrict network access to the service.
