+Subject: [PATCH] [3.5] bpo-32981: Fix catastrophic backtracking vulns
+ (GH-5955) (#6034)
+
+* Prevent low-grade poplib REDOS (CVE-2018-1060)
+
+The regex to test a mail server's timestamp is susceptible to
+catastrophic backtracking on long evil responses from the server.
+
+Happily, the maximum length of malicious inputs is 2K thanks
+to a limit introduced in the fix for CVE-2013-1752.
+
+A 2KB evil response from the mail server would result in small slowdowns
+(milliseconds vs. microseconds) accumulated over many apop calls.
+This is a potential DOS vector via accumulated slowdowns.
+
+Replace it with a similar non-vulnerable regex.
+
+The new regex is RFC compliant.
+The old regex was non-compliant in edge cases.
+
+* Prevent difflib REDOS (CVE-2018-1061)
+
+The default regex for IS_LINE_JUNK is susceptible to
+catastrophic backtracking.
+This is a potential DOS vector.
+
+Replace it with an equivalent non-vulnerable regex.
+
+Also introduce unit and REDOS tests for difflib.

++Regexes in difflib and poplib were vulnerable to catastrophic backtracking.
++These regexes formed potential DOS vectors (REDOS). They have been
++refactored. This resolves CVE-2018-1060 and CVE-2018-1061.
