Description

Microsoft Office for Mac contains a flaw that may allow an attacker to gain access to unauthorized privileges. The issue is triggered due to the installation folder having weak permissions, allowing a local attacker to replace binaries with malicious copies. When a user or administrator executes the alternate binary, the attacker's code will run with the same privileges as the user executing the program. This can be leveraged to take control of a system.
