Petr Viktorin 4766d1200f [3.12] gh-121650: Encode newlines in headers, and verify headers are sound (GH-122233) (#122599) ... * gh-121650: Encode newlines in headers, and verify headers are sound (GH-122233) - Encode header parts that contain newlines 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. - Verify that email headers are well-formed This should fail for custom fold() implementations that aren't careful about newlines.
