Description

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.

How to fix

Upgrade to a fixed version: Apache Libcloud 0.11.0. Check the vendor advisory for mitigations.
