CVE-2018-12029

Priority
Description
A race condition in the nginx module in Phusion Passenger 3.x through 5.x
before 5.3.2 allows local escalation of privileges when a non-standard
passenger_instance_registry_dir with insufficiently strict permissions is
configured. Replacing a file with a symlink after the file was created, but
before it was chowned, leads to the target of the link being chowned via
the path. Targeting sensitive files such as root's crontab file allows
privilege escalation.
