  <title>libsndfile: Buffer overflow</title>
  <synopsis>
    A buffer overflow vulnerability has been discovered in libsndfile.

  <affected>
    <package name="media-libs/libsndfile" auto="yes" arch="*">
      <unaffected range="ge">1.0.17-r1</unaffected>

    <p>
    libsndfile is a library for reading and writing various formats of
    audio files including WAV and FLAC.
    </p>

  <description>
    <p>
    Robert Buchholz of the Gentoo Security team discovered that the
    flac_buffer_copy() function does not correctly handle FLAC streams with
    variable block sizes which leads to a heap-based buffer overflow
    (CVE-2007-4974).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit this vulnerability by enticing a user
    to open a specially crafted FLAC file or network stream with an
    application using libsndfile. This might lead to the execution of
    arbitrary code with privileges of the user playing the file.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libsndfile users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libsndfile-1.0.17-r1&quot;</code>
  </resolution>
