A remote code execution issue exists in the way that Windows Journal parses specially crafted files. The issue could lead to remote code execution if a user opens a specially crafted Journal file. If a user is logged on with administrative rights, an attacker who successfully exploits this issue 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.
