Thanks, got the mail now. We'll check on it asap.

Thanks. Let me know if you need any additional information. We prefer 1-2 business days notice of public release disclosure so we can coordinate on our end as well. Please let me know any new developments and/or timelines as they are confirmed (even if tentative).

Committed fix for one of the CVE's, note that I think we could make the CVE's public. It's no secret that corrupt files can crash Blender in various ways.

Do you have any updates on the other issues reported? To date, it appears only CVE-2017-2901 (TALOS-2017-0408) is fixed although TALOS-2017-0451 is also referenced above.

Closing this report, use T52924 instead.
