Overview

passenger is a modern web server and application server for Ruby, Python and Node.js, optimized for performance, low memory usage and ease of use.

Affected versions of this package are vulnerable to Improper Access Control. Passenger-managed malicious application, upon spawning a child process, could report an arbitrary different PID back to Passenger's process manager. If the malicious application then generates an error, it would cause Passenger's process manager to kill said reported arbitrary PID.
