    <p>
    xine-lib is a multimedia library which can be utilized to create
    multimedia frontends.

  <description>
    <p>
    xine-lib contains two stack-based overflows and one heap-based
    overflow. In the code reading VCD disc labels, the ISO disc label is
    copied into an unprotected stack buffer of fixed size. Also, there is a
    buffer overflow in the code that parses subtitles and prepares them for
    display (XSA-2004-4). Finally, xine-lib contains a heap-based overflow
    in the DVD sub-picture decoder (XSA-2004-5).
    </p>
    <p>
    (Please note that the VCD MRL issue mentioned in XSA-2004-4 was fixed
    with GLSA 200408-18.)
    </p>
  </description>
  <impact type="normal">
    <p>
    With carefully-crafted VCDs, DVDs, MPEGs or subtitles, an attacker may
    cause xine-lib to execute arbitrary code with the permissions of the
    user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All xine-lib users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv &quot;&gt;=media-libs/xine-lib-1_rc6&quot;
    # emerge &quot;&gt;=media-libs/xine-lib-1_rc6&quot;</code>
  </resolution>
