Will Dormann has reported some vulnerabilities in the iseemedia LPViewer ActiveX control, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors within the "url()", "toolbar()", and "enableZoomPastMax()" methods provided by the iseemedia LPViewer (LPControl.dll) ActiveX control. These can be exploited to cause stack-based buffer overflows when a user is tricked into visiting a malicious website.
Successful exploitation allows execution of arbitrary code.
Solution: Set the kill-bit for the affected ActiveX control.
