VERIFY ADVISORY:
http://secunia.com/advisories/28307/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
Georgia SoftWorks SSH2 Server 7.x
http://secunia.com/product/17066/

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.

PROVIDED AND/OR DISCOVERED BY:
