  <affected>
    <package name="sys-cluster/singularity" auto="yes" arch="*">
      <unaffected range="ge">3.7.4</unaffected>
      <vulnerable range="lt">3.7.4</vulnerable>

  <background>
    <p>Singularity is the container platform for performance sensitive
      workloads.
    </p>
  </background>
  <description>
    <p>Singularity always uses the default remote endpoint,
      ‘cloud.syslabs.io’, for action commands using the ‘library://’
      URI rather than the configured remote endpoint.
    </p>
  </description>
  <impact type="high">
    <p>An attacker that that can push a malicious container to the default
      remote endpoint could execute code on hosts that fetch the container.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Singularity users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-cluster/singularity-3.7.4"
    </code>
