Greetings again. This is a stub security review, given that one of the co-authors is a Security AD. This document is a pile of ASN.1 that updates earlier ASN.1 modules in various security documents. The Security Considerations section says, in total: This document itself does not have any security considerations. The ASN.1 modules keep the same bits-on-the-wire as the modules that they replace. I agree with that assessment. --Paul Hoffman
