Thomas Pollet reported a possible integer overflow vulnerability in the
PNG image handling in the file filter/image-png.c.
</p>
</description>
<impact type="high">
<p>
A malicious user might be able to execute arbitrary code with the
privileges of the user running CUPS (usually lp), or cause a Denial of
Service by sending a specially crafted PNG image to the print server.
The vulnerability is exploitable via the network if 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-r8&quot;</code>
</resolution>
