Description:
Two vulnerabilities have been discovered in Ourgame GLWorld, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors in the HanGamePluginCn18.HanGamePluginCn18.1 ActiveX control (HanGamePluginCn18.dll) when handling strings passed as arguments to the "hgs_startGame()" and "hgs_startNotify()" methods. These can be exploited to cause stack-based buffer overflows by passing overly long strings as argument to the affected methods.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 2.6.1.29. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
Provided and/or discovered by:
Discovered as a 0-day.
