Amazon Linux 2023 Security Advisory: ALAS-2025-792
Advisory Release Date: 2025-01-06 19:21 Pacific
Advisory Updated Date: 2025-01-09 13:05 Pacific
Severity: Medium

Issue Overview:

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. (CVE-2024-52804)
