The Corel / Micrografx ActiveCGM Browser ActiveX control contains multiple buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The Corel ActiveCGM Browser is an ActiveX control that allows viewing of Computer Graphic Metafiles (CGMs) in a web browser. The ActiveCGM Browser ActiveX control, which is provided by acgm.dll, contains multiple buffer overflows. Note that the control was created by Micrografx, which was acquired by Corel.
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.
