<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>

<description>
<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>
</description>
<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 &quot;&gt;=net-print/cups-1.1.23&quot;</code>
</resolution>
