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.

<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 ">=dev-libs/openssl-0.9.8g-r2"</code>
|
|
</resolution>
