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

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.
