Summary: [C++] Improve flatbuffers verification limits
Key: ARROW-11559
URL: https://issues.apache.org/jira/browse/ARROW-11559
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Antoine Pitrou
Assignee: Antoine Pitrou

[https://github.com/apache/arrow/pull/9349#issuecomment-775295349] :
Flatbuffers is able to encode a virtually unbounded of schema fields in a small
buffer size. Verifying that many fields with the Flatbuffers verifier seems to
result in potentially unlimited verification times, which is a denial of
service risk.
The way to mitigate this risk is to pass an appropriate max_tables and/or
max_depth limit to the Flatbuffers verifier.
