Multiple vulnerabilities have been identified in Ourgame GLWorld, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system. These issues are caused by buffer overflow errors in the "HanGamePluginCn18.dll" ActiveX control when processing overly long arguments passed to the "hgs_startGame()" and "hgs_startNotify()" methods, which could be exploited by remote attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
Note: This vulnerability is currently being exploited in the wild.
