<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.

Xpdf is an open source viewer for Portable Document Format (PDF) files. The
|
|
Common UNIX Printing System (CUPS) is a cross-platform print spooler that
|
|
includes some Xpdf code.

<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.

There is no known workaround at this time.

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>
