1 Overall description SA3 would like to thank IETF Transport Area Working Group (TSVWG) for notifying SA3 of the vulnerabilities related to SCTP-AUTH and DTLS over SCTP. SA3 agrees that the vulnerabilities are serious – they are affecting confidentiality, integrity, replay, and availability. Supporting DTLS over SCTP in N2, Xn, F1, and E1 interfaces has been made mandatory from Release 15 onwards. Therefore, SA3’s understanding is that it is important to solve all the security vulnerabilities, including the availability vulnerabilities. Since the problem is related to the use of DTLS with SCTP, SA3’s understanding is that the solution should be based on DTLS, and the solution should not rely on unsupported DTLS features SA3 kindly asks TSVWG to work on and publish a solution as soon as possible. 2 Actions To: IETF Transport Area Working Group (TSVWG) ACTION: SA3 kindly asks IETF Transport Area Working Group (TSVWG) to take the above information into account and keep SA3 updated on TSVWG’s. 3 Dates of next TSG SA WG 3 meetings SA3#112 14 - 18 August 2023 Goteborg, Sweden SA3#113 6 - 10 November 2023 Chicago, USA |
