<title>Xpdf, CUPS: Multiple integer overflows</title>
<synopsis>
Multiple integer overflows were discovered in Xpdf, potentially resulting
in execution of arbitrary code upon viewing a malicious PDF file. CUPS
includes Xpdf code and therefore is vulnerable to the same issues.

Common UNIX Printing System (CUPS) is a cross-platform print spooler that

Chris Evans discovered multiple integer overflow issues in Xpdf.

<impact type="normal">
<p>
An attacker could entice an user to open a specially-crafted PDF file,
potentially resulting in execution of arbitrary code with the rights of the
user running Xpdf. By enticing an user to directly print the PDF file to a
CUPS printer, an attacker could also crash the CUPS spooler or execute
arbitrary code with the rights of the CUPS spooler, which is usually the
"lp" user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Xpdf users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r5"</code>
<p>
All CUPS users should also upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.1.20-r5"</code>
