|
<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>OpenSSL incorrectly handles memory in the TLS heartbeat extension,
|
|
leading to information disclosure of 64kb per request, possibly
|
|
including private keys (“Heartbleed bug”, OpenSSL 1.0.1 only,
|
|
CVE-2014-0160).
|
|
</li>
|
|
<li>The Montgomery ladder implementation of OpenSSL improperly handles
|
|
swap operations (CVE-2014-0076).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could exploit these issues to disclose information,
|
|
including private keys or other sensitive information, or perform
|
|
side-channel attacks to obtain ECDSA nonces.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>Disabling the tls-heartbeat USE flag (enabled by default) provides a
|
|
workaround for the CVE-2014-0160 issue.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All OpenSSL users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1g"
|
|
</code>
|
|
|
|
<p>Note: All services using OpenSSL to provide TLS connections have to be
|
|
restarted for the update to take effect. Utilities like
|
|
app-admin/lib_users can aid in identifying programs using OpenSSL.
|
|
</p>
|
|
|
|
<p>As private keys may have been compromised using the Heartbleed attack,
|
|
it is recommended to regenerate them.
|
|
</p>
