<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>
