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.

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).

<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.

<workaround>

<p>
|
|
There is no known workaround at this time.

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All CUPS users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-print/cups-1.1.23"</code>
