protocols.
</p>

<description>
<p>Multiple vulnerabilities have been discovered in GnuTLS. Please review
the CVE identifiers and Lucky Thirteen research paper referenced below
for details.
</p>
</description>
<impact type="normal">
<p>A remote attacker could sent a specially crafted packet to cause a
Denial of Service condition. Additionally, a remote attacker could
perform man-in-the-middle attacks to recover plaintext data.
</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-2.12.23-r1"
</code>
