  - CVE-2014-2323
    Jann Horn discovered that specially crafted host names
    can be used to inject arbitrary MySQL queries in
    lighttpd servers using the MySQL virtual hosting module
    (mod_mysql_vhost).

  This only affects installations with the lighttpd-mod-mysql-vhost
  binary package installed and in use.

  - CVE-2014-2324
    Jann Horn discovered that specially crafted host names
    can be used to traverse outside of the document root
    under certain situations in lighttpd servers using
    either the mod_mysql_vhost, mod_evhost, or
    mod_simple_vhost virtual hosting modules.

  Servers not using these modules are not affected."
