  <background>
    <p>Boost is a set of C++ libraries, including the Boost.Regex library to
      process regular expressions.
    </p>
  </background>
  <description>
    <p>It was discovered that Boost incorrectly sanitized ‘next_size’ and
      ‘max_size’ parameter in ordered_malloc() function when allocating
      memory.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could provide a specially crafted application-specific
      file (requiring runtime memory allocation to be processed correctly),
      that, when opened with an application using Boost C++ source libraries,
      possibly resulting in execution of arbitrary code with the privileges of
      the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Boost users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/boost-1.74.0-r2"
    </code>
