The parsed forms of MIME headers and multipart forms can consume substantially more memory than the size of the input data. A malicious input containing a very large number of headers or form parts can cause excessively large memory allocations. Set limits on the size of MIME data: Reader.NextPart and Reader.NextRawPart limit the the number of headers in a part to 10000. Reader.ReadForm limits the total number of headers in all FileHeaders to 10000. Both of these limits may be set with with GODEBUG=multipartmaxheaders=<values>. Reader.ReadForm limits the number of parts in a form to 1000. This limit may be set with GODEBUG=multipartmaxparts=<value>. Thanks for Jakob Ackermann (@das7pad) for reporting this issue.
