build(deps): update dependency tornado to v6.4.2 [security] (hotfix/8.4)
Metadata
Current evaluation
Tornado 6.4.2 hotfix for 8.4 was closed unmerged because the imminent 8.5.0 release would replace the 8.4.x branch.
Resolution: closed stale
Reason: The PR was abandoned after @mr-cal noted on November 27, 2024 that 8.5.0 was already a release candidate and would replace 8.4.x the following week, making this branch-specific backport unnecessary.

### GitHub Vulnerability Alerts
#### [CVE-2024-52804](https://redirect.github.com/tornadoweb/tornado/security/advisories/GHSA-8w49-h785-mj3c)
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.
See also CVE-2024-7592 for a similar vulnerability in cpython.
