Description

The remote host contains the ActiveCGM ActiveX control, which supports viewing of CGM files in a web browser.

The version of this control on the remote host is reportedly affected by multiple buffer overflows. If an attacker can trick a user on the affected host into visiting a specially crafted web page, he may be able to leverage these issues to execute arbitrary code on the host subject to the user's privileges.
