Harden ssl module against LibreSSL :cve:`2018-8970`.
|
|
X509_VERIFY_PARAM_set1_host() is called with an explicit namelen. A new test

ensures that NULL bytes are not allowed.

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`. Patch by Jamie
|

Davis.
