KPdf and KWord both include vulnerable Xpdf code to handle PDF files, making them vulnerable to the execution of arbitrary code.

KPdf is a KDE-based PDF viewer included in the kdegraphics package. KWord is a KDE-based word processor also included in the koffice package.
KPdf and KWord both include Xpdf code to handle PDF files. This Xpdf code is vulnerable to several heap overflows (GLSA 200512-08) as well as several buffer and integer overflows discovered by Chris Evans (CESA-2005-003).
An attacker could entice a user to open a specially crafted PDF file with Kpdf or KWord, potentially resulting in the execution of arbitrary code with the rights of the user running the affected application.
There is no known workaround at this time.
