  <title>CUPS: Multiple vulnerabilities</title>
  <synopsis>
    Multiple vulnerabilities have been found in CUPS, ranging from local Denial
    of Service attacks to the remote execution of arbitrary code.

    <p>
    The Common UNIX Printing System (CUPS) is a cross-platform print
    spooler, hpgltops is a CUPS filter handling printing of HPGL files and
    lppasswd is a program used locally to manage spooler passwords.

    <p>
    CUPS makes use of vulnerable Xpdf code to handle PDF files
    (CAN-2004-1125). Furthermore, Ariel Berkman discovered a buffer
    overflow in the ParseCommand function in hpgl-input.c in the hpgltops
    program (CAN-2004-1267). Finally, Bartlomiej Sieka discovered several
    problems in the lppasswd program: it ignores some write errors
    (CAN-2004-1268), it can leave the passwd.new file in place
    (CAN-2004-1269) and it does not verify that passwd.new file is
    different from STDERR (CAN-2004-1270).
    </p>

  <impact type="high">
    <p>
    The Xpdf and hpgltops vulnerabilities may be exploited by a remote
    attacker to execute arbitrary code by sending specific print jobs to a
    CUPS spooler. The lppasswd vulnerabilities may be exploited by a local
    attacker to write data to the CUPS password file or deny further
    password modifications.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CUPS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-print/cups-1.1.23"</code>
  </resolution>
