A remote code execution vulnerability exists in Microsoft Windows when a specially crafted Journal file is opened in Windows Journal. An attacker who successfully exploited this vulnerability could cause arbitrary code to execute in the context of the current user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system.
