  <title>AWStats: Remote code execution</title>
  <synopsis>
    AWStats fails to validate certain input, which could lead to the remote
    execution of arbitrary code or to the leak of information.

    <p>
    AWStats is an advanced log file analyzer and statistics generator.
    </p>

  <description>
    <p>
    When 'awstats.pl' is run as a CGI script, it fails to validate specific
    inputs which are used in a Perl open() function call. Furthermore, a
    user could read log file content even when plugin rawlog was not
    enabled.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could supply AWStats malicious input, potentially
    allowing the execution of arbitrary code with the rights of the web
    server. He could also access raw log contents.
    </p>
  </impact>
  <workaround>
    <p>
    Making sure that AWStats does not run as a CGI script will avoid the
    issue, but we recommend that users upgrade to the latest version, which
    fixes these bugs.
    </p>
  </workaround>
  <resolution>
    <p>
    All AWStats users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-misc/awstats-6.3-r2"</code>
    <p>
    Note: Users with the vhosts USE flag set should manually use
    webapp-config to finalize the update.
    </p>
