DescriptionA flaw was discovered in Go's net/http standard library package. 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 issue permitted a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to a denial of service.A flaw was discovered in Go's net/http standard library package.
