<p>
Poppler is a cross-platform PDF rendering library originally based on
Xpdf. KOffice is an integrated office suite for KDE. KWord is the
KOffice word processor. KPDF is a KDE-based PDF viewer included in the
kdegraphics package.

<description>
<p>
Alin Rad Pop (Secunia Research) discovered several vulnerabilities in
the "Stream.cc" file of Xpdf: An integer overflow in the
DCTStream::reset() method and a boundary error in the
CCITTFaxStream::lookChar() method, both leading to heap-based buffer
overflows (CVE-2007-5392, CVE-2007-5393). He also discovered a boundary
checking error in the DCTStream::readProgressiveDataUnit() method
causing memory corruption (CVE-2007-4352). Note: Gentoo's version of
Xpdf is patched to use the Poppler library, so the update to Poppler
will also fix Xpdf.
</p>
</description>
<impact type="normal">
<p>
By enticing a user to view or process a specially crafted PDF file with
KWord or KPDF or a Poppler-based program such as Gentoo's viewers Xpdf,
ePDFView, and Evince or the CUPS printing system, a remote attacker
could cause an overflow, potentially resulting in the execution of
arbitrary code with the privileges of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Poppler users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.1-r1"</code>
<p>
All KPDF users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r3"</code>
<p>
All KDE Graphics Libraries users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r3"</code>
<p>
All KWord users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r2"</code>
<p>
All KOffice users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/koffice-1.6.3-r2"</code>
