+Subject: [PATCH] httputil: Fix quadratic performance of cookie parsing
+
+Maliciously-crafted cookies can cause Tornado to
+spend an unreasonable amount of CPU time and block
+the event loop.
+
+This change replaces the quadratic algorithm with
+a more efficient one. The implementation is copied
+from the Python 3.13 standard library (the
+previous one was from Python 3.5).
+
+Fixes CVE-2024-52804
+See CVE-2024-7592 for a similar vulnerability in cpython.
+
+Thanks to github.com/kexinoh for the report.
