<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. Please review the
CVE identifiers and the upstream advisory referenced below for details:
</p>
<ul>
<li>RSA silently downgrades to EXPORT_RSA [Client] (Reclassified)
(CVE-2015-0204)
</li>
<li>Segmentation fault in ASN1_TYPE_cmp (CVE-2015-0286)</li>
<li>ASN.1 structure reuse memory corruption (CVE-2015-0287)</li>
<li>X509_to_X509_REQ NULL pointer deref (CVE-2015-0288)</li>
<li>PKCS7 NULL pointer dereferences (CVE-2015-0289)</li>
<li>Base64 decode (CVE-2015-0292)</li>
<li>DoS via reachable assert in SSLv2 servers (CVE-2015-0293)</li>
<li>Use After Free following d2i_ECPrivatekey error (CVE-2015-0209)</li>
</ul>
<p>The following issues affect OpenSSL 1.0.2 only which is not part of the
supported Gentoo stable tree:
</p>
<ul>
<li>OpenSSL 1.0.2 ClientHello sigalgs DoS (CVE-2015-0291)</li>
<li>Multiblock corrupted pointer (CVE-2015-0290)</li>
<li>Segmentation fault in DTLSv1_listen (CVE-2015-0207)</li>
<li>Segmentation fault for invalid PSS parameters (CVE-2015-0208)</li>
<li>Empty CKE with client auth and DHE (CVE-2015-1787)</li>
<li>Handshake with unseeded PRNG (CVE-2015-0285)</li>
</ul>

<impact type="normal">
<p>A remote attacker can utilize multiple vectors to cause Denial of
Service or Information Disclosure.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All OpenSSL 1.0.1 users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1l-r1"
</code>
<p>All OpenSSL 0.9.8 users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8z_p5-r1"
</code>
<p>Packages which depend on the OpenSSL library need to be restarted for
the upgrade to take effect. Some packages may need to be recompiled.
Tools such as revdep-rebuild may assist in identifying some of these
packages.
