NVD Description

Note: Versions mentioned in the description apply only to the upstream python311-tornado6 package and not the python311-tornado6 package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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