summary: Memory exhaustion in multipart form parsing in net/textproto and net/http
description: |-
    When parsing a multipart form (either explicitly with Request.ParseMultipartForm
    or implicitly with Request.FormValue, Request.PostFormValue, or
    Request.FormFile), limits on the total size of the parsed form were not applied
    to the memory consumed while reading a single form line. This permits a
    maliciously crafted input containing very long lines to cause allocation of
    arbitrarily large amounts of memory, potentially leading to memory exhaustion.

    With fix, the ParseMultipartForm function now correctly limits the maximum size
    of form lines.
