  <title>libsndfile: User-assisted execution of arbitrary code</title>
  <synopsis>
    Multiple heap-based buffer overflow vulnerabilities in libsndfile might
    allow remote attackers to execute arbitrary code.

  <background>
    <p>
    libsndfile is a C library for reading and writing files containing
    sampled sound.
    </p>
  </background>
  <description>
    <p>
    The following vulnerabilities have been found in libsndfile:
    </p>
    <ul>
    <li>Tobias Klein reported that the header_read() function in
    src/common.c uses user input for calculating a buffer size, possibly
    leading to a heap-based buffer overflow (CVE-2009-1788).</li>
    <li>The
    vendor reported a boundary error in the aiff_read_header() function in
    src/aiff.c, possibly leading to a heap-based buffer overflow
    (CVE-2009-1791).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted AIFF
    or VOC file in a program using libsndfile, possibly resulting in 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 libsndfile users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libsndfile-1.0.20&quot;</code>
  </resolution>
