The E-Book Systems FlipViewer ActiveX control contains multiple stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
E-Book Systems FlipViewer is software for viewing "FlipBooks." FlipViewer includes an ActiveX control called FViewerLoading, which is provided by the file FlipViewerX.dll . This ActiveX control contains multiple stack buffer overflow vulnerabilities. Vulnerable properties include UID, Opf, PAGENO, LaunchMode, SubID, BookID, LibraryID, SubURL, and LoadOpf.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.
