<synopsis>

overflow issue, potentially resulting in the remote execution of arbitrary
code.

<p>
The Common UNIX Printing System (CUPS) is a cross-platform print
spooler. It makes use of Xpdf code to handle PDF files.

<description>
<p>
The Decrypt::makeFileKey2 function in Xpdf's Decrypt.cc
insufficiently checks boundaries when processing /Encrypt /Length tags
in PDF files (GLSA 200501-28).
</p>
</description>
<impact type="normal">
<p>
This issue could be exploited by a remote attacker to execute
arbitrary code by sending a malicious print job to a CUPS spooler.
</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-r1&quot;</code>
</resolution>
