  <access>local, remote</access>
  <affected>
    <package name="dev-libs/libxml2" auto="yes" arch="*">
      <unaffected range="ge">2.9.2</unaffected>
      <vulnerable range="lt">2.9.2</vulnerable>
    </package>
  </affected>
  <background>
    <p>libxml2 is the XML C parser and toolkit developed for the Gnome project.</p>
  </background>
  <description>
    <p>parser.c in libxml2 before 2.9.2 does not properly prevent entity
      expansion even when entity substitution has been disabled.
    </p>
  </description>
  <impact type="normal">
    <p>A context-dependent attacker could entice a user to a specially crafted
      XML file using an application linked against libxml2, possibly resulting
      in a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libxml2 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/libxml2-2.9.2"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying these packages.
    </p>
