<background>
<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.
</p>
</background>
<description>
<p>Multiple vulnerabilities have been found in OpenSSL:</p>
<ul>
<li>Timing differences for decryption are exposed by CBC mode encryption
in OpenSSL’s implementation of DTLS (CVE-2011-4108).
</li>
<li>A policy check failure can result in a double-free error when
X509_V_FLAG_POLICY_CHECK is set (CVE-2011-4109).
</li>
<li>Clients and servers using SSL 3.0 handshakes do not clear the block
cipher padding, allowing a record to contain up to 15 bytes of
uninitialized memory, which could include sensitive information
(CVE-2011-4576).
</li>
<li>Assertion errors can occur during the handling of malformed X.509
certificates when OpenSSL is built with RFC 3779 support
(CVE-2011-4577).
</li>
<li>A resource management error can occur when OpenSSL’s server gated
cryptography (SGC) does not properly handle handshake restarts
(CVE-2011-4619).
</li>
<li>Invalid parameters in the GOST block cipher are not properly handled
by the GOST ENGINE(CVE-2012-0027).
</li>
<li>An incorrect fix for CVE-2011-4108 creates an unspecified
vulnerability for DTLS applications using OpenSSL (CVE-2012-0050).
</li>
</ul>
</description>
<impact type="normal">
<p>A remote attacker may be able to cause a Denial of Service or obtain
sensitive information, including plaintext passwords.
</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 "&gt;=dev-libs/openssl-1.0.0g"
</code>
</resolution>
