+Subject: [PATCH] SSL: upgrade the default DH parameters
+
+We have been using as default DH parameters the 1024-bit MODP group.
+This is now considered insecure, and applications should use the
+2048-bit at a minimum [1]. This commit therefore replaces the parameters
+with the 2048-bit MODP group from [2].
+
+To double check the data, use openssl asn1parse to verify that the prime
+matches. For instance:
+
+1) put the encoded string in a `encoded.txt` file (c&p from the source,
+ removing the double quotes)
+2) put the hexadecimal value of the 2048-bit group in a `reference.txt`
+ file (c&p from [2])
+3) compare the output of openssl asn1parse with the reference. For
+ instance like this:
+
+ $ diff <(openssl asn1parse < encoded.txt | grep -m 1 INTEGER | perl -pe 's/.*://; s/\n//') <(perl -0777 -pe 's/\s//g' reference.txt) && echo OK
+ OK
+
+[1] https://datatracker.ietf.org/doc/html/rfc8247#section-2.4
+[2] https://datatracker.ietf.org/doc/html/rfc3526#section-3
+
+[ChangeLog][QtNetwork][QSslDiffieHellmanParameters] The default
+Diffie-Hellman parameters are now using the 2048-bit MODP group from
+RFC 3526.
+
+Pick-to: 6.6 6.5 6.2 5.15
