+.. section: Security
+The IDNA codec decoder used on DNS hostnames by :mod:`socket` or
+:mod:`asyncio` related name resolution functions no longer involves a
+quadratic algorithm. This prevents a potential CPU denial of service if an
+out-of-spec excessive length hostname involving bidirectional characters
+were decoded. Some protocols such as :mod:`urllib` http :samp:`3{xx}` redirects
+potentially allow for an attacker to supply such a name.
+Individual labels within an IDNA encoded DNS name will now raise an error
+early during IDNA decoding if they are longer than 1024 unicode characters
+given that each decoded DNS label must be 63 or fewer characters and the
+entire decoded DNS name is limited to 255. Only an application presenting a
+hostname or label consisting primarily of :rfc:`3454` section 3.1 "Nothing"
+characters to be removed would run into of this new limit. See also
+:rfc:`5894` section 6 and :rfc:`3491`.
