    <p>GnuTLS is a secure communications library implementing the SSL, TLS and
      DTLS protocols and technologies around them.

    <p>A null pointer dereference while decoding a status response TLS
      extension with valid contents was discovered in GnuTLS.

  <impact type="normal">
    <p>A remote attacker could possibly cause a Denial of Service condition.</p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GnuTLS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-libs/gnutls-3.5.13"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying some of these packages.
