Perl's read grows the buffer to the requested length before reading, so the declared Content-Length determines the allocation.\n\nAn attacker can trigger this through any route whose dispatch specification has a % body-parameter match, such as sub (POST + %name=), sending a Content-Length far larger than the body actually sent.
