Secdir Last Call review of -??
by Alan DeKok
I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The document defines a language used to read and write descriptions of management information. It is not intended to be used within an "on the wire" internet protocol. As such, the usual "on the wire" security issues do not apply. The "Security Considerations" looks OK. I would suggest adding a caution about reading data from untrusted sources. Document readers have a long history of being attacked by malformed documents. e.g.: YANG parsers need to be robust with respect to malformed documents. Reading malformed documents from unknown or untrusted sources could result in an attacker gaining privileges of the user running the YANG parser. In an extreme situation, the entire machine could be compromised. Alan DeKok.
