  "title": "Microsoft Outlook Remote Code Execution Vulnerability",
  "description": "\u003Cp\u003EA remote code execution vulnerability exists in the way that Microsoft Outlook parses specially modified rule export files.\u003C/p\u003E\n\u003Cp\u003EAn attacker who successfully exploited this vulnerability could take 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. Systems such as workstations and terminal servers where Microsoft Outlook is used are at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.\u003C/p\u003E\n\u003Cp\u003EIn an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted email message to the user and then convincing the user to open the email and import an attached .rwz (rule export) file. Exploitation of this vulnerability requires that a user open a specially crafted email message with an affected version of Microsoft Outlook, download a malicious attachment, and manually import the contents of the attachment using the Outlook user interface.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting the way that Microsoft Outlook parses rule export files.\u003C/p\u003E",
