    <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&#39;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>
