MS14-017  Vulnerabilities in Microsoft Word and Office Web Apps Could Allow Remote Code Execution

2014-04-08 This security update resolves one publicly disclosed vulnerability and two privately reported vulnerabilities in Microsoft Office. The most severe of these vulnerabilities could allow remote code execution if a specially crafted file is opened in an affected version of Microsoft Office software. An attacker who successfully these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Vulnerabilities addressed in this bulletin:

Microsoft Office File Format Converter Vulnerability

A remote code execution vulnerability exists in the way that affected Microsoft Office software converts specially crafted files. An attacker who successfully exploited this vulnerability could run arbitrary code as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
CVE-2014-1757

Microsoft Word Stack Overflow Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Word parses specially crafted files. An attacker who successfully exploited this vulnerability could run arbitrary code as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
CVE-2014-1758

Word RTF Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Microsoft Word parses specially crafted files. An attacker who successfully exploited this vulnerability could run arbitrary code as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
