      ECDH downgrade bug fix. · b15f8769
      Dr. Stephen Henson authored
      
      
      Fix bug where an OpenSSL client would accept a handshake using an
      ephemeral ECDH ciphersuites with the server key exchange message omitted.
      
      Thanks to Karthikeyan Bhargavan for reporting this issue.

      Fix various certificate fingerprint issues. · 684400ce
      Dr. Stephen Henson authored
      
      
      By using non-DER or invalid encodings outside the signed portion of a
      certificate the fingerprint can be changed without breaking the signature.
      Although no details of the signed portion of the certificate can be changed
      this can cause problems with some applications: e.g. those using the
      certificate fingerprint for blacklists.
      
      1. Reject signatures with non zero unused bits.
      
      If the BIT STRING containing the signature has non zero unused bits reject
      the signature. All current signature algorithms require zero unused bits.
      
      2. Check certificate algorithm consistency.
      
      Check the AlgorithmIdentifier inside TBS matches the one in the
      certificate signature. NB: this will result in signature failure
      errors for some broken certificates.
      
      3. Check DSA/ECDSA signatures use DER.
      
      Reencode DSA/ECDSA signatures and compare with the original received
      signature. Return an error if there is a mismatch.
      
      This will reject various cases including garbage after signature
      (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
      program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
      (negative or with leading zeroes).

      Tighten session ticket handling · d663df23
      Emilia Kasper authored
      
      
      Tighten client-side session ticket handling during renegotiation:
      ensure that the client only accepts a session ticket if the server sends
      the extension anew in the ServerHello. Previously, a TLS client would
      reuse the old extension state and thus accept a session ticket if one was
      announced in the initial ServerHello.
