Tornado is a Python web framework and asynchronous networking library. Thealgorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2sometimes has quadratic complexity, leading to excessive CPU consumptionwhen parsing maliciously-crafted cookie headers. This parsing occurs in theevent loop thread and may block the processing of other requests. Version6.4.2 fixes the issue.
