Severity: grave

Justification: user security hole
Hi,
a new libcloud was released, fixing a MITM vulnerability in the TLS/SSL
certificates verification. Basically the hostname/CN check is done using
a wrong regular expression which will match even superset of the
hostname.
See http://libcloud.apache.org/security.html and
https://github.com/apache/libcloud/commit/f2af5502dae3ac63e656dd1b7d5f29cc82ded401
and please upload an isolated fix to unstable, since we're in freeze.
Regards,
