It is ambiguous if a CA must not issue when such a CAA Resource Record Set is encountered, or if such a Resource Record Set is implicit permission to issue. Given that the intent of the RFC is clear (such a CAA Resource Record Set is implicit permission to issue), we are proposing the following change to allow for CAA processing consistent with the intent of the RFC. The following motion has been proposed by Corey Bonnell of Trustwave and endorsed by Tim Hollebeek of Digicert and Mads Egil Henriksveen of Buypass. -- MOTION BEGINS -- This ballot modifies the “Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates” as follows, based upon Version 1.5.6: In section 220.127.116.11, add this sentence: CAs MAY treat a non-empty CAA Resource Record Set that does not contain any issue property tags (and also does not contain any issuewild property tags when performing CAA processing for a Wildcard Domain Name) as permission to issue, provided that no records in the CAA Resource Record Set otherwise prohibit issuance. to the end of this paragraph: When processing CAA records, CAs MUST process the issue, issuewild, and iodef property tags as specified in RFC 6844, although they are not required to act on the contents of the iodef property tag. Additional property tags MAY be supported, but MUST NOT conflict with or supersede the mandatory property tags set out in this document. CAs MUST respect the critical flag and not issue a certificate if they encounter an unrecognized property with this flag set. -- MOTION ENDS – The procedure for approval of this ballot is as follows: Discussion (7+ days) Start Time: 2018-03-07 19:00:00 UTC End Time: 2018-04-03 19:00:00 UTC Vote for approval (7 days) Start Time: 2018-04-03 19:00:00 UTC End Time: 2018-04-10 19:00:00 UTC Corey Bonnell Senior Software Engineer t: +1 412.395.2233 Trustwave | SMART SECURITY ON DEMAND www.trustwave.com <CA-Browser Forum BR 1.5.6-ballot 219 redline.doc>_______________________________________________ Public mailing list Public@cabforum.org https://cabforum.org/mailman/listinfo/public 本信件可能包含中華電信股份有限公司機密資訊,非指定之收件者,請勿蒐集、處理或利用本信件內容,並請銷毀此信件. 如為指定收件者,應確實保護郵件中本公司之營業機密及個人資料,不得任意傳佈或揭露,並應自行確認本郵件之附檔與超連結之安全性,以共同善盡資訊安全與個資保護責任.
