  <title>webapp-config: Insecure temporary file handling</title>
  <synopsis>
    The webapp-config utility insecurely creates temporary files in a world
    writable directory, potentially allowing the execution of arbitrary
    commands.

    <p>
    webapp-config is a Gentoo Linux utility to help manage the installation
    of web-based applications.

  <description>
    <p>
    Eric Romang discovered webapp-config uses a predictable temporary
    filename while processing certain options, resulting in a race
    condition.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation of the race condition would allow an attacker
    to disrupt the operation of webapp-config, or execute arbitrary shell
    commands with the privileges of the user running webapp-config. A local
    attacker could use a symlink attack to create or overwrite files with
    the permissions of the user running webapp-config.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All webapp-config users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/webapp-config-1.11"</code>
