Description
### Summary
net/http: request smuggling through invalid chunked data: The net/http package accepts data in the chunked transfer encoding containing an invalid chunk-size line terminated by a bare LF. When used in conjunction with a server or proxy which incorrectly interprets a bare LF in a chunk extension as part of the extension, this could permit request smuggling.
