-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 CVE-2012-3446: Apache Libcloud - possible MITM due to invalid regular expression used to validate the target server hostname Severity: Medium Vendor: The Apache Software Foundation Versions Affected: Apache Libcloud 0.4.2 to 0.11.1 Versions prior to 0.4.2 don't perform any target server SSL certificate validation. Description: When establishing a secure (SSL / TLS) connection to a target server an invalid regular expression has been used for performing the hostname verification. Subset instead of the full target server hostname has been marked an an acceptable match for the given hostname. For example, certificate with a hostname field of "aexample.com" was considered a valid certificate for domain "example.com". Mitigation: Users should upgrade to the latest version (0.11.1) which includes a fix. Credit: This issue was discovered by researchers from the University of Texas at Austin (Martin Georgiev, Suman Jana and Vitaly Shmatikov).
