Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2024-11-22 06:21:15 UTC 
+- Parsing of the cookie header is now much more efficient. The older algorithm sometimes had
+  quadratic performance which allowed for a denial-of-service attack in which the server would spend
+  excessive CPU time parsing cookies and block the event loop. This change fixes CVE-2024-7592.

Apparently they've reused CPython's CVE.
