Vulnerability Description
iseemedia is a software development company focused on the commercialization of advanced, rich content adaptation and distribution solutions for Web applications. iseemedia's platforms are used by websites worldwide. The iseemedia LPViewer ActiveX control contains multiple buffer overflow vulnerabilities. The vulnerabilities are caused due to boundary errors within several methods provided by the iseemedia LPViewer ActiveX control. By convincing a user to visit a malicious web page, an attacker may be able to execute arbitrary code with the privileges of the user.
