    <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 vulnerabilities have been discovered in OpenSSL. Please review
      the CVE identifiers and the International Association for Cryptologic
      Research’s (IACR) paper, “Make Sure DSA Signing Exponentiations
      Really are Constant-Time” for further details.
    </p>
  </description>
  <impact type="normal">
    <p>Remote attackers could cause a Denial of Service condition or have other
      unspecified impacts. Additionally, a time based side-channel attack may
      allow a local attacker to recover a private DSA key.
    </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-1.0.2j"
    </code>
