-Subject: [PATCH] bpo-39503: CVE-2020-8492: Fix AbstractBasicAuthHandler
- (GH-18284)
-
-Upstream-Status: Backport
-(https://github.com/python/cpython/commit/0b297d4ff1c0e4480ad33acae793fbaf4bf015b4)
-
-CVE: CVE-2020-8492
-
-The AbstractBasicAuthHandler class of the urllib.request module uses
-an inefficient regular expression which can be exploited by an
-attacker to cause a denial of service. Fix the regex to prevent the
-catastrophic backtracking. Vulnerability reported by Ben Caller
-and Matt Schwager.
-
-AbstractBasicAuthHandler of urllib.request now parses all
-WWW-Authenticate HTTP headers and accepts multiple challenges per
-header: use the realm of the first Basic challenge.
