During the spawning of a malicious Passenger-managed application,
SpawningKit in Phusion Passenger 5.3.x before 5.3.2 allows such
applications to replace key files or directories in the spawning
communication directory with symlinks. This then could result in arbitrary
reads and writes, which in turn can result in information disclosure and
privilege escalation.
