Log Message:
go119: update to 1.19.6 (security)

This minor release includes 4 security fixes following the security policy:

- path/filepath: path traversal in filepath.Clean on Windows

  On Windows, the filepath.Clean function could transform an invalid path such
  as a/../c:/b into the valid path c:\b. This transformation of a relative (if
  invalid) path into an absolute path could enable a directory traversal
  attack.  The filepath.Clean function will now transform this path into the
  relative (but still invalid) path .\c:\b.

  Thanks to RyotaK (https://ryotak.net) for reporting this issue.

  This is CVE-2022-41722 and Go issue https://go.dev/issue/57274.

- net/http, mime/multipart: denial of service from excessive resource
  consumption

  Multipart form parsing with mime/multipart.Reader.ReadForm can consume
  largely unlimited amounts of memory and disk files. This also affects form
  parsing in the net/http package with the Request methods FormFile, FormValue,
  ParseMultipartForm, and PostFormValue.

  ReadForm takes a maxMemory parameter, and is documented as storing "up to
  maxMemory bytes +10MB (reserved for non-file parts) in memory". File parts
  which cannot be stored in memory are stored on disk in temporary files. The
  unconfigurable 10MB reserved for non-file parts is excessively large and can
  potentially open a denial of service vector on its own. However, ReadForm did
  not properly account for all memory consumed by a parsed form, such as map
  entry overhead, part names, and MIME headers, permitting a maliciously
  crafted form to consume well over 10MB. In addition, ReadForm contained no
  limit on the number of disk files created, permitting a relatively small
  request body to create a large number of disk temporary files.

  ReadForm now properly accounts for various forms of memory overhead, and
  should now stay within its documented limit of 10MB + maxMemory bytes of
  memory consumption. Users should still be aware that this limit is high and
  may still be hazardous.

  ReadForm now creates at most one on-disk temporary file, combining multiple
  form parts into a single temporary file. The mime/multipart.File interface
  type's documentation states, "If stored on disk, the File's underlying
  concrete type will be an *os.File.". This is no longer the case when a form
  contains more than one file part, due to this coalescing of parts into a
  single file. The previous behavior of using distinct files for each form part
  may be reenabled with the environment variable
  GODEBUG=multipartfiles=distinct.

  Users should be aware that multipart.ReadForm and the http.Request methods
  that call it do not limit the amount of disk consumed by temporary files.
  Callers can limit the size of form data with http.MaxBytesReader.

  Thanks to Arpad Ryszka and Jakob Ackermann (@das7pad) for reporting this
  issue.

  This is CVE-2022-41725 and Go issue https://go.dev/issue/58006.

- crypto/tls: large handshake records may cause panics

  Both clients and servers may send large TLS handshake records which cause
  servers and clients, respectively, to panic when attempting to construct
  responses.

  This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable
  session resumption (by setting Config.ClientSessionCache to a non-nil value),
  and TLS 1.3 servers which request client certificates (by setting
  Config.ClientAuth >= RequestClientCert).

  Thanks to Marten Seemann for reporting this issue.

  This is CVE-2022-41724 and Go issue https://go.dev/issue/58001.

- net/http: avoid quadratic complexity in HPACK decoding

  A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in
  the HPACK decoder, sufficient to cause a denial of service from a small
  number of small requests.

  This issue is also fixed in golang.org/x/net/http2 v0.7.0, for users manually
  configuring HTTP/2.

  Thanks to Philippe Antoine (Catena cyber) for reporting this issue.

  This is CVE-2022-41723 and Go issue https://go.dev/issue/57855.
