Description

A local privilege escalation is caused by Overwolf loading and executing certain dynamic link library files from a user-writeable folder in SYSTEM context on launch. This allows an attacker with unprivileged access to the system to run arbitrary code with SYSTEM privileges by placing a malicious .dll file in the respective location.
