<title>OpenSSL: Information Disclosure</title>
<synopsis>Multiple Information Disclosure vulnerabilities in OpenSSL allow
remote attackers to obtain sensitive information via various vectors.

<affected>
<package name="dev-libs/openssl" auto="yes" arch="*">
<unaffected range="ge">1.0.1g</unaffected>
<vulnerable range="lt">1.0.1g</vulnerable>
</package>
</affected>
<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>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>
</resolution>
