Improper Resource Shutdown or Release in TYPO3 extension

Wrong usage of the TYPO3 FAL API results in copies of processed files being saved to the /var/transient/ folder of a TYPO3 website on every frontend request. This can result in Denial of Service, since the webspace may be filled up with image files simply by crafting a large amount of requests to the website.
