libcloud before 0.4.0 does not verify SSL certificates for HTTPS connections, which allows remote attackers to spoof certificates and bypass intended access restrictions via a man-in-the-middle (MITM) attack. This is due to an upstream issue with python's SSL module rather than directly with libcloud.
Libcloud does not set the scrub_data parameter for the DigitalOcean API, which allows local users to obtain sensitive information by leveraging a new VM.
Apache Libcloud 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.
