<title>OpenSSL: Remote execution of arbitrary code</title>
<synopsis>
OpenSSL contains a vulnerability allowing execution of arbitrary code or a
Denial of Service.

<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>
Andy Polyakov reported a vulnerability in the OpenSSL toolkit, that is
caused due to an unspecified off-by-one error within the DTLS
implementation.
</p>
</description>
<impact type="high">
<p>
A remote attacker could exploit this issue to execute arbitrary code or
cause a Denial of Service. Only clients and servers explicitly using
DTLS are affected, systems using SSL and TLS are not.
</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-0.9.8f"</code>
</resolution>
