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>

<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 ">=net-print/cups-1.2.12-r7"</code>
|
|
