  <description>
    <p>Multiple vulnerabilities have been discovered in GnuPG and Libgcrypt.
      Please review the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>An unauthenticated remote attacker may be able to execute arbitrary code
      with the privileges of the user running GnuPG, cause a Denial of Service
      condition, or bypass security restrictions. Additionally, a side-channel
      attack may allow a local attacker to recover a private key, please review
      “Flush+Reload: a High Resolution, Low Noise, L3 Cache Side-Channel
      Attack” in the References section for further details.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GnuPG 2.0 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-crypt/gnupg-2.0.22"
    </code>
    
    <p>All GnuPG 1.4 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-crypt/gnupg-1.4.16"
    </code>
    
    <p>All Libgcrypt users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
