Tobias Klein found heap overflow in the VOC parser of libsndfile: [1], [2].
Libsndfile developers reported on the fixed heap overflow in the AIFF
parser: [2].

        <p>Tobias Klein reports:</p>
          <p>libsndfile contains a heap buffer overflow vulnerability
          while parsing malformed VOC (Creative Voice) media files. The
          vulnerability may be exploited by a (remote) attacker to
          execute arbitrary code in the context of an application using
          the libsndfile library.</p>
        <p>Additionally, libsndfile developers report on the unspecified
        buffer overflow in the AIFF parser.</p>
