## Description

In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18 and 7.4.x below
7.4.6, when HTTP file uploads are allowed, supplying overly long filenames
or field names could lead PHP engine to try to allocate oversized memory
storage, hit the memory limit and stop processing the request, without
cleaning up temporary files created by upload request. This potentially
could lead to accumulation of uncleaned temporary files exhausting the disk
space on the target server.
