| Subject: [PATCH] bpo-35746: Fix segfault in ssl's cert parser (GH-11569) | |||
| Fix a NULL pointer deref in ssl module. The cert parser did not handle CRL | |||
| distribution points with empty DP or URI correctly. A malicious or buggy | |||
| certificate can result into segfault. | |||

| Subject: [PATCH] bpo-30458: Disallow control chars in http URLs. (GH-12755) | |||
| MIME-Version: 1.0 | |||
| Content-Type: text/plain; charset=UTF-8 | |||
| Content-Transfer-Encoding: 8bit | |||
| Disallow control chars in http URLs in urllib.urlopen. This addresses a potential security problem for applications that do not sanity check their URLs where http request headers could be injected. | |||
| Disable https related urllib tests on a build without ssl (GH-13032) | |||
| These tests require an SSL enabled build. Skip these tests when python is built without SSL to fix test failures. | |||
| Use http.client.InvalidURL instead of ValueError as the new error case's exception. (GH-13044) | |||
