Description Vincent Danen 2012-08-03 19:45:26 UTC
A man-in-the-middle vulnerability was reported [1] in Apache Libcloud, due to an invalid regular expression used to validate the target server hostname.  When establishing an SSL/TLS connection to a target server, a subset of the full target server hostname was marked as an acceptable match for the given hostname (such as a certificate specifying "aexample.com" being considered acceptable for "example.com").  Upstream version 0.11.1 includes a fix for this flaw.
