DESCRIPTION:
A security issue has been reported in the Apache Libcloud, which can
be exploited by malicious people to conduct spoofing attacks.

The security issue is caused due to the use of an invalid regular
expression when verifying the hostname of the SSL server
certificates, which leads to a subset of the hostname being accepted
as a valid hostname. This can be exploited to e.g. conduct
Man-in-the-Middle (MitM) attacks.

The security issue is reported in versions 0.4.2 and later.

SOLUTION:
Update to version 0.11.1.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Martin Georgiev, Suman Jana, and Vitaly Shmatikov,
University of Texas.
