  <background>
    <p>
    CUPS provides a portable printing layer for UNIX-based operating
    systems.
    </p>
  </background>
  <description>
    <p>
    Multiple vulnerabilities have been reported in CUPS:
    </p>
    <ul>
    <li>regenrecht (VeriSign iDefense) discovered that the
    cgiCompileSearch() function used in several CGI scripts in CUPS'
    administration interface does not correctly calculate boundaries when
    processing a user-provided regular expression, leading to a heap-based
    buffer overflow (CVE-2008-0047).</li>
    <li>Helge Blischke reported a
    double free() vulnerability in the process_browse_data() function when
    adding or removing remote shared printers (CVE-2008-0882).</li>
    <li>Tomas Hoger (Red Hat) reported that the gif_read_lzw() function
    uses the code_size value from GIF images without properly checking it,
    leading to a buffer overflow (CVE-2008-1373).</li>
    <li>An unspecified
    input validation error was discovered in the HP-GL/2 filter
    (CVE-2008-0053).</li>
    </ul>
  </description>
  <impact type="high">
    <p>
    A local attacker could send specially crafted network packets or print
    jobs and possibly execute arbitrary code with the privileges of the
    user running CUPS (usually lp), or cause a Denial of Service. The
    vulnerabilities are exploitable via the network when CUPS is sharing
    printers remotely.
    </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 &quot;&gt;=net-print/cups-1.2.12-r7&quot;</code>
  </resolution>
