Vulnerability Information

Microsoft Video Control Remote Code Execution Vulnerability – CVE-2016-7248

A remote code execution vulnerability exists when Microsoft Video Control fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the 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.

To exploit the vulnerability, an attacker would have to convince a user to open either a specially crafted file or application from either a webpage or an email message. The update addresses the vulnerability by correcting how Microsoft Video Control handles objects in memory.

Note that where the severity is indicated as Critical in the Affected Software and Vulnerability Severity Ratings table, the Outlook Preview Pane is an attack vector for CVE-2016-7248.
