S/MIME and X.509 certificates.

<p>
iDefense has reported two potential buffer overflow vulnerabilities
found by researcher "regenrecht" in the code implementing the SSLv2
protocol.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could send a specially crafted SSL master key to a
server using NSS for the SSLv2 protocol, or entice a user to connect to
a malicious server with a client-side application using NSS like one of
the Mozilla products. This could trigger the vulnerabilities and result
in the possible execution of arbitrary code with the rights of the
vulnerable application.
</p>
</impact>
<workaround>
<p>
Disable the SSLv2 protocol in the applications using NSS.
</p>
</workaround>
<resolution>
<p>
All NSS users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/nss-3.11.5&quot;</code>
</resolution>
