  <synopsis>Multiple vulnerabilities have been found in HPLIP, the worst of
    which may allow execution of arbitrary code.

  <background>
    <p>The Hewlett-Packard Linux Imaging and Printing system (HPLIP) provides
      drivers for HP's inkjet and laser printers, scanners and fax machines. 
    </p>
  </background>
  <description>
    <p>Two vulnerabilities have been found in HPLIP:</p>
    
    <ul>
      <li>The "hpmud_get_pml()" function in pml.c contains a boundary error
        which could cause a stack-based buffer overflow (CVE-2010-4267).
      </li>
      <li>The "send_data_to_stdout()" function in hpcupsfax.cpp creates
        insecure temporary files (CVE-2011-2722).
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>A remote attacker might send specially crafted SNMP reponses, possibly
      resulting in execution of arbitrary code or a Denial of Service
      condition. Furthermore, a local attacker could perform symlink attacks to
      overwrite arbitrary files.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All HPLIP users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-print/hplip-3.11.10"
    </code>
