<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 buffer overflows exist in OpenSSL's handling of TLS certificates for client authentication.</p>
</description>
<impact type="normal">
<p>It is believed that, while unlikely, code execution is possible in certain system configurations.</p>
</impact>
<workaround>
<p>Users operating TLS servers may consider disabling TLS client authentication, if it is being used, until fixes are applied.</p>
</workaround>
<resolution>
<p>All OpenSSL 3 users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-3.0.7"
</code>
</resolution>
