CRITICAL:
Highly critical
IMPACT:
System access
WHERE:
>From remote
SOFTWARE:
Ourgame GLWorld 2.x
http://secunia.com/product/16420/
DESCRIPTION:
Some 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 within the
GLCHAT.GLChatCtrl.1 ActiveX control (GLChat.ocx) when handling the
"ConnectAndEnterRoom()" method. These can be exploited to cause
stack-based buffer overflows by passing overly long arguments to the
affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are confirmed in version 2.7.0.8 including
GLChat.ocx version 2.5.1.32. 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.
