    GnuTLS is a free TLS 1.0 and SSL 3.0 implementation for the GNU
    project.

  <description>
    <p>
    A vulnerability has been discovered in the record packet parsing
    in the GnuTLS library. Additionally, a flaw was also found in the RSA
    key export functionality.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit this vulnerability and cause a
    Denial of Service to any application that utilizes the GnuTLS library.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GnuTLS users should remove the existing installation and
    upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --unmerge gnutls
    # emerge --ask --oneshot --verbose net-libs/gnutls</code>
    <p>
    Due to small API changes with the previous version, please do
    the following to ensure your applications are using the latest GnuTLS
    that you just emerged.
    </p>
    <code>
    # revdep-rebuild --soname-regexp libgnutls.so.1[0-1]</code>
    <p>
    Previously exported RSA keys can be fixed by executing the
    following command on the key files:
    </p>
    <code>
    # certtool -k infile outfile</code>
  </resolution>
