Description:
void has discovered a vulnerability in Kingsoft Antivirus Online Update Module, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the KUpdateObj2 Class ActiveX control (UpdateOcx2.dll) when processing arguments passed to the "SetUninstallName()" method. This can be exploited to cause a heap-based buffer overflow by passing an overly long argument to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in UpdateOcx2.dll version 2007.12.29.29. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
