Roman Danyliw has entered the following ballot position for draft-ietf-payload-vp9-13: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-payload-vp9/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thank you to Rifaat Shekh-Yusef for the SECDIR review. ** Section 8. Thanks for mentioning the denial of service via computational complexity issue. Since the VP9 spec doesn’t say it, but other codec documents typically do (RFC6386 and draft-ietf-cellar-ffv1), please also considering adding a comment about processing un-trusted input. Roughly: OLD This RTP payload format and its media decoder do not exhibit any significant non-uniformity in the receiver-side computational complexity for packet processing, and thus are unlikely to pose a denial-of-service threat due to the receipt of pathological data. Nor does the RTP payload format contain any active content. NEW Implementations of this RTP payload format need to take appropriate security considerations into account. It is extremely important for the decoder to be robust against malicious payloads and ensure that they do not cause the decoder to overrun its allocated memory. An overrun in allocated memory could lead to arbitrary code execution by an attacker. The same applies to the encoder, even though problems in encoders are typically rarer. This RTP payload format and its media decoder do not exhibit any significant non-uniformity in the receiver-side computational complexity for packet processing, and thus are unlikely to pose a denial-of-service threat due to the receipt of pathological data. Nor does the RTP payload format contain any active content. ** Nits -- Section 3. Editorial. Per “Layers are designed (and MUST be encoded) …”, it seems odd to have normative language as a parenthetical. -- Section 3. Editorial. s/a the term/the term/ -- Section 6.1.2.
