+Subject: [PATCH] Backport fix for bpo-38804
+
+The regex http.cookiejar.LOOSE_HTTP_DATE_RE was vulnerable to regular
+expression denial of service (REDoS). The regex contained multiple
+overlapping \s* capture groups. A long sequence of spaces can trigger
+bad performance.
+
+See https://github.com/python/cpython/pull/17157 and https://pyup.io/posts/pyup-discovers-redos-vulnerabilities-in-top-python-packages/
