Multiple Microsoft Office Memory Corruption Vulnerabilities
Multiple remote code execution vulnerabilities exist in Microsoft Office software when the Office software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the 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.
Microsoft Office Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists in Microsoft Office software when an attacker instantiates an affected Office application via a COM control. An attacker who successfully exploited the vulnerability could gain elevated privileges and break out of the Internet Explorer sandbox.
Microsoft Outlook for Mac Spoofing Vulnerability
A spoofing vulnerability exists when Microsoft Outlook for Mac does not sanitize HTML or treat it in a safe manner. An attacker who successfully exploited this vulnerability could trick a user by redirecting them to a malicious website. The malicious website could spoof content or be used as a pivot to chain an attack with other vulnerabilities in web services.
