    It was discovered that Apache Commons HttpClient did not properly verify the Common Name or subjectAltName
    fields of X.509 certificates. An attacker could exploit this to perform a machine-in-the-middle attack to
    view sensitive information or alter encrypted communications. This issue only affected Ubuntu 12.04 LTS.
