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=4007 -------------------------------------- Type: Technical Reported by: KIKUCHI Masashi <kikuchi@lepidum.co.jp> Section: 7.3. Original Text ------------- Note: To help avoid pipeline stalls, ChangeCipherSpec is an independent TLS protocol content type, and is not actually a TLS handshake message. Corrected Text -------------- Note: To avoid ChangeCipherSpec being transmitted in mix with other handshake fragments in one record, ChangeCipherSpec is an independent TLS protocol content type, and is not actually a TLS handshake message. To help avoid pipeline stalls, ChangeCipherSpec is sent from both the server and the client. Notes ----- The original text can be read like we can handle ChangeCipherSpec asynchronously. This is harmful and may be a cause of CCS Injection vulnerability. Instructions: ------------- This errata is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC5246 (draft-ietf-tls-rfc4346-bis-10) -------------------------------------- Title : The Transport Layer Security (TLS) Protocol Version 1.2 Publication Date : August 2008 Author(s) : T.
