Description:
7jdg has reported a vulnerability in Xunlei Thunder, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the DPClient.Vod.1 ActiveX control (DapPlayer_Now.dll) when handling arguments passed to the "DownURL2()" method. This can be exploited to cause a buffer overflow by passing an overly long argument to the affected method.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in version 5.6.9.344. Other versions may also be affected.

Solution:
Set the kill-bit for the affected ActiveX control.
