In 1.1.1/1.1.1a we used SSL_CB_HANDSHAKE_START + and SSL_CB_HANDSHAKE_DONE. Experience has shown that many applications get + confused by this and assume that a TLSv1.2 renegotiation has started. This + can break KeyUpdate handling. Instead we no longer signal the start and end + of a post handshake message exchange (although the messages themselves are + still signalled). This could break some applications that were expecting + the old signals. However without this KeyUpdate is not usable for many + applications. + [Matt Caswell] + + *) Fix a bug in the computation of the endpoint-pair shared secret used + by DTLS over SCTP. This breaks interoperability with older versions + of OpenSSL like OpenSSL 1.1.0 and OpenSSL 1.0.2. There is a runtime + switch SSL_MODE_DTLS_SCTP_LABEL_LENGTH_BUG (off by default) enabling + interoperability with such broken implementations. However, enabling + this switch breaks interoperability with correct implementations. + + *) Fix a use after free bug in d2i_X509_PUBKEY when overwriting a + re-used X509_PUBKEY object if the second PUBKEY is malformed. + [Bernd Edlinger] + + *) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0(). + [Richard Levitte] + + *) Remove the 'dist' target and add a tarball building script. The + 'dist' target has fallen out of use, and it shouldn't be + necessary to configure just to create a source distribution. + [Richard Levitte] + Changes between 1.1.1 and 1.1.1a [20 Nov 2018] *) Timing vulnerability in DSA signature generation diff --git a/crypto/openssl/CONTRIBUTING b/crypto/openssl/CONTRIBUTING index c0eed39e34b2..5d717763d51e 100644 --- a/crypto/openssl/CONTRIBUTING +++ b/crypto/openssl/CONTRIBUTING @@ -57,7 +57,7 @@ guidelines: 7.
