<p>
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
purpose cryptography library.

<description>
<p>
Ossi Herrala and Jukka Taimisto of Codenomicon discovered two
vulnerabilities:
</p>
<ul>
<li>
A double free() call in the TLS server name extension (CVE-2008-0891).
</li>
<li>
The OpenSSL client code does not properly handle servers that omit the
Server Key Exchange message in the TLS handshake (CVE-2008-1672).
</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could connect to a vulnerable server, or entice a
daemon to connect to a malicious server, causing a Denial of Service of
the daemon in both cases.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All OpenSSL users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/openssl-0.9.8g-r2&quot;</code>
</resolution>
