+Subject: [PATCH] Be more strict in parsing Content-Length
+
+Validate that we are only parsing digits and nothing else. RFC7230 is
+explicit in that the Content-Length can only exist of 1*DIGIT and may
+not include any additional sign information.
+
+The Python int() function parses `+10` as `10` which means we were more
+lenient than the standard intended.
+
+Backport:
+* Patch refresh - no functional change.

+Subject: [PATCH] Update tests to remove invalid chunked encoding chunk-size
+
+RFC7230 states the following:
+
+     chunk          = chunk-size [ chunk-ext ] CRLF
+                      chunk-data CRLF
+     chunk-size     = 1*HEXDIG
+
+Where chunk-ext is:
+
+     chunk-ext      = *( ";" chunk-ext-name [ "=" chunk-ext-val ] )
+
+Only if there is a chunk-ext should there be a `;` after the 1*HEXDIG.
+And a chunk-ext that is empty is invalid.

+Subject: [PATCH] Error when receiving back Chunk Extension
+
+Waitress discards chunked extensions and does no further processing on
+them, however it failed to validate that the chunked encoding extension
+did not contain invalid data.
+
+We now validate that if there are any chunked extensions that they are
+well-formed, if they are not and contain invalid characters, then
+Waitress will now correctly return a Bad Request and stop any further
+processing of the request

+Subject: [PATCH 5/6] This patch is a backport of commit d9bdfa0
+
+From: Bert JW Regeer <bertjw@regeer.org>
+Date: Sat, 12 Mar 2022 18:48:26 -0700
+Subject: [PATCH] Validate chunk size in Chunked Encoding are HEXDIG
+
+RFC7230 states that a chunk-size should be 1*HEXDIG, this is now
+validated before passing the resulting string to int() which would also
+parse other formats for hex, such as: `0x01` as `1` and `+0x01` as `1`.
+This would lead to a potential for a frontend proxy server and waitress
+to disagree on where a chunk started and ended, thereby potentially
+leading to request smuggling.
+
+With the increased validation if the size is not just hex digits,
+Waitress now returns a Bad Request and stops processing the request.

+Subject: [PATCH] Remove extraneous calls to .strip() in Chunked Encoding
+
+To be valid chunked encoding we should not be removing any whitespace as
+the standard does not allow for optional whitespace.
+
+If whitespace is encountered in the wrong place, it should lead to a 400
+Bad Request instead.
+
