|
||
<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>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>

<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 ">=dev-libs/openssl-1.0.0g"
|
||
</code>
