Microsoft RMS Sharing App for Mac Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists in RMS Sharing App for Mac in the way it allows an attacker to load unsigned binaries. An attacker could then install programs; view, change, or delete data with the logged in user’s privileges.

To exploit this vulnerability, an attacker would first have to get access to the victim’s system.

The update addresses the vulnerability by correcting how the app validates signatures.
