KDE Security Advisory: kpdf/xpdf multiple integer overflows
Original Release Date: 2005-12-07
URL: http://www.kde.org/info/security/advisory-20051207-1.txt

         CAN-2005-3191

         CAN-2005-3193


1. Systems affected:

         KDE 3.2.0 up to including KDE 3.5.0
	KOffice 1.3.0 up to including KOffice 1.4.2


2. Overview:

         kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains
         multiple integer overflow vulnerabilities that allow specially
	crafted pdf files, when opened, to overflow a heap allocated
	buffer and execute arbitrary code.


3. Impact:

         Remotely supplied pdf files can be used to execute arbitrary
	code on the client machine.


4. Solution:

         Source code patches have been made available which fix these
         vulnerabilities. Contact your OS vendor / binary package provider
         for information about how to obtain updated binary packages.
