  <title>GnomeVFS, libcdaudio: CDDB response overflow</title>
  <synopsis>
    The GnomeVFS and libcdaudio libraries contain a buffer overflow that can be
    triggered by a large CDDB response, potentially allowing the execution of
    arbitrary code.

    <p>
    GnomeVFS is a filesystem abstraction library for the GNOME desktop
    environment. libcdaudio is a multi-platform CD player development
    library. They both include code to query CDDB servers to get Audio CD
    track titles.

  <description>
    <p>
    Joseph VanAndel has discovered a buffer overflow in Grip when
    processing large CDDB results (see GLSA 200503-21). The same overflow
    is present in GnomeVFS and libcdaudio code.
    </p>
  </description>
  <impact type="normal">
    <p>
    A malicious CDDB server could cause applications making use of GnomeVFS
    or libcdaudio libraries to crash, potentially allowing the execution of
    arbitrary code with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GnomeVFS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose gnome-base/gnome-vfs</code>
    <p>
    All libcdaudio users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libcdaudio-0.99.10-r1&quot;</code>
