Microsoft Office Word Multiple Vulnerabilities ( 11 August 2010 )

1. Word Record Parsing Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Office Word handles malformed records inside a specially crafted Word file. An attacker who successfully exploited this vulnerability 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.

2. Word RTF Parsing Engine Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Office Word parses rich text data. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.

3. Word RTF Parsing Buffer Overflow Vulnerability

An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.

4. Word HTML Linked Objects Memory Corruption Vulnerability
