DTLS protocols and technologies around them.

<description>
<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 ">=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.
