<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>It was discovered that OpenSSL allow malicious servers to send very
large primes to a client during DH(E) based TLS handshakes.
</p>
</description>
<impact type="normal">
<p>A remote attacker, by sending large prime to client during DH(E) TLS
handshake, could possibly cause a Denial of Service condition.
</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-1.0.2o-r6"
</code>
