<background>
<p>
Xpdf, Kpdf and GPdf are PDF file viewers that run under the X
Window System. Kpdf and GPdf both contain Xpdf code. Kpdf is also part
of kdegraphics.
</p>
</background>
<description>
<p>
Xpdf, Kpdf and GPdf do not handle a broken table of embedded
TrueType fonts correctly. After detecting such a table, Xpdf, Kpdf and
GPdf attempt to reconstruct the information in it by decoding the PDF
file, which causes the generation of a huge temporary file.
</p>
</description>
<impact type="normal">
<p>
A remote attacker may cause a Denial of Service by creating a
specially crafted PDF file, sending it to a CUPS printing system (which
uses Xpdf), or by enticing a user to open it in Xpdf, Kpdf, or GPdf.
</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-r10"</code>
<p>
All GPdf users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r1"</code>
<p>
All Kpdf users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.2-r3"</code>
<p>
All KDE Split Ebuild Kpdf users should upgrade to the latest
version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.1-r1"</code>
