Microsoft Word fails to properly parse crafted rich text content

Vulnerability Note VU#555489

Original Release Date: 2007-05-09 | Last Revised: 2007-05-09


Microsoft Word fails to properly parse rich text content and may allow a remote, unauthenticated attacker to execute arbitrary code.


Microsoft Word does not properly validate rich text within the contents of a file. When Word opens and parses a specially crafted file, memory corruption can occur and can allow arbitrary code execution. By convincing a user to open a specially crafted Word file, an attacker may be able to execute arbitrary code.


A remote, unauthenticated attacker may be able to execute arbitrary code or access the system with the privileges of the local user.
