Subject: [PATCH] 00435: gh-121650: Encode newlines in headers, and verify
|
||||||
|
headers are sound (GH-122233)
|
||||||
|
|
||||||
|
Per RFC 2047:
|
||||||
|
|
||||||
|
> [...] these encoding schemes allow the
|
||||||
|
> encoding of arbitrary octet values, mail readers that implement this
|
||||||
|
> decoding should also ensure that display of the decoded data on the
|
||||||
|
> recipient's terminal will not cause unwanted side-effects
|
||||||
|
|
||||||
|
It seems that the "quoted-word" scheme is a valid way to include
|
||||||
|
a newline character in a header value, just like we already allow
|
||||||
|
undecodable bytes or control characters.
|
||||||
|
They do need to be properly quoted when serialized to text, though.
|
||||||
|
|
||||||
|
This should fail for custom fold() implementations that aren't careful
|
||||||
|
about newlines.
|
||||||
|
|
||||||
|
