This indicates an attempt to exploit a buffer overflow vulnerability in the Lianzong ActiveX control, part of a Chinese gaming platform.
The ActiveX control (CLSID:61F5C358-60FB-4A23-A312-D2B556620F20) is vulnerable to a buffer overflow attack through the "hgs_startgame()" and "hgs_startnotify()" functions. By passing an overly long string, a remote attacker can execute arbitrary code on vulnerable computers.
Impact
System Compromise: remote attackers can gain control of vulnerable systems.
