Microsoft DirectShow MJPEG Decompression Vulnerability( 15 April 2009 )

A remote code execution vulnerability exists in the way Microsoft DirectShow handles supported format files. This vulnerability could allow code execution if a user opened a specially crafted MJPEG file. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
