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 Security Feature Bypass Vulnerability
A security feature bypass vulnerability exists in Microsoft Office software due to an invalidly signed binary. An attacker who successfully exploited the vulnerability could use a similarly configured binary to host malicious code. A defender would then not be able to rely on a valid binary signature to differentiate between a known good and a malicious binary.
