  <synopsis>

    vulnerability which could lead to execution of arbitrary commands.

  <affected>
    <package name="www-apps/gallery" auto="yes" arch="*">
      <unaffected range="ge">1.4.4_p2</unaffected>

  <background>
    <p>
    Gallery is a PHP script for maintaining online photo albums.
    </p>
  </background>
  <description>
    <p>
    The upload handling code in Gallery places uploaded files in a
    temporary directory. After 30 seconds, these files are deleted if they
    are not valid images. However, since the file exists for 30 seconds, a
    carefully crafted script could be initiated by the remote attacker
    during this 30 second timeout. Note that the temporary directory has to
    be located inside the webroot and an attacker needs to have upload
    rights either as an authenticated user or via "EVERYBODY".
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could run arbitrary code as the user running PHP.
    </p>
  </impact>
  <workaround>
    <p>
    There are several workarounds to this vulnerability:
    </p>
    <ul>
    <li>Make sure that your temporary directory is not contained in the
    webroot; by default it is located outside the webroot.</li>
    <li>Disable upload rights to all albums for "EVERYBODY"; upload is
    disabled by default.</li>
    <li>Disable debug and dev mode; these settings are disabled by
    default.</li>
    <li>Disable allow_url_fopen in php.ini.</li>
    </ul>
  </workaround>
  <resolution>
    <p>
    All Gallery users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=www-apps/gallery-1.4.4_p2"
    # emerge "&gt;=www-apps/gallery-1.4.4_p2"</code>
  </resolution>
