** Description changed:
[Impact]
Users of urllib3 are unable to securely access websites who's certificates
use IP based subject alternative names; this includes openstack client tooling
which uses urllib3 via requests.
[Test Case]
- TBD
+ Deploy and configure a server with TLS and an IP based SAN cert with a
locally trusted CA.
+
+ import urllib3
+
+ http = urllib3.PoolManager()
+ r = http.request('GET', 'https://192.168.1.2')
+
+ will fail
+
[Regression Potential]
Cherry picked fix comes from a later urllib3 release which has tested fine
for IP SAN usage in later OpenStack release deployments.
[Original Bug Report]
urllib3 fails to validate certificates with IP address based SAN's.
Fixed upstream:
