  <title>PEAR::MDB2: Information disclosure</title>
  <synopsis>

    attackers to obtain sensitive information.

  <affected>
    <package name="dev-php/PEAR-MDB2" auto="yes" arch="*">
      <unaffected range="ge">2.5.0_alpha1</unaffected>

  <background>
    <p>
    PEAR::MDB2 is a database abstraction layer for PHP aimed to provide a
    common API for all supported relational database management systems. A
    LOB ("large object") is a database field holding binary data.
    </p>
  </background>
  <description>
    <p>
    priyadi discovered that the request to store a URL string as a LOB is
    treated as a request to retrieve and store the contents of the URL.
    </p>
  </description>
  <impact type="normal">
    <p>
    If an application using PEAR::MDB2 allows input of LOB values via a web
    form, remote attackers could use the application as an indirect proxy
    or obtain sensitive information, including "file://" URLs local to the
    web server.
    </p>
  </impact>
  <workaround>
    <p>
    As a workaround, manually filter input before storing it as a LOB in
    PEAR::MDB2.
    </p>
  </workaround>
  <resolution>
    <p>
    All PEAR::MDB2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-php/PEAR-MDB2-2.5.0_alpha1"</code>
  </resolution>
