The following errata report has been submitted for RFC5246,
"The Transport Layer Security (TLS) Protocol Version 1.2".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=5246&eid=2865

--------------------------------------
Type: Technical
Reported by: Alfredo Pironti <alfredo.pironti@inria.fr>

Section: 7.4.4

Original Text
-------------
struct {
    ClientCertificateType certificate_types<1..2^8-1>;
    SignatureAndHashAlgorithm
      supported_signature_algorithms<2^16-1>;
    DistinguishedName certificate_authorities<0..2^16-1>;
} CertificateRequest;

Corrected Text
--------------
struct {
    ClientCertificateType certificate_types<1..2^8-1>;
    SignatureAndHashAlgorithm
      supported_signature_algorithms<2..2^16-2>;
    DistinguishedName certificate_authorities<0..2^16-1>;
} CertificateRequest;

Notes
-----
The supported_signature_algorithms field is a variable length array. As such ceiling and floor should be specified, and they should be multiple of the base type (which is two bytes long in this case). See section 7.4.1.4.1 for a valid definition of this field.

Instructions:
