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.

<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.

<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.
