NVD Description

Note: Versions mentioned in the description apply only to the upstream pcs package and not the pcs package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is fixed in 6.5.5.
