CVE-2020-16853

An elevation of privilege vulnerability exists when the OneDrive for Windows Desktop application improperly handles symbolic links. An attacker who successfully exploited this vulnerability could overwrite a targeted file with an elevated status.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and delete a targeted file with an elevated status.

The update addresses this vulnerability by correcting where the OneDrive updater performs file writes while running with elevation.
