  </description>
  <impact type="normal">
    <p>A context-dependent attacker could entice a user to open a specially
      crafted file using an application linked against Pixman, 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 Pixman users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-libs/pixman-0.32.4"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying these packages.
