In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below
7.4.3, when using file upload functionality, if upload progress tracking is
enabled, but session.upload_progress.cleanup is set to 0 (disabled), and
the file upload fails, the upload procedure would try to clean up data that
does not exist and encounter null pointer dereference, which would likely
lead to a crash.
