Quick fix

PYSEC-2012-12 — apache-libcloud: upgrade to the fixed version with the command below.

pip install --upgrade 'apache-libcloud>=0.11.1'

Details

Apache Libcloud before 0.11.1 uses an incorrect regular expression during verification of whether the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate.
