Synopsis
========
KPDF includes code from xpdf that is vulnerable to a stack-based buffer
overflow.
Background
==========
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.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/koffice < 1.6.3-r1 >= 1.6.3-r1
2 app-office/kword < 1.6.3-r1 >= 1.6.3-r1
3 kde-base/kdegraphics < 3.5.7-r1 >= 3.5.7-r1
4 kde-base/kpdf < 3.5.7-r1 >= 3.5.7-r1
-------------------------------------------------------------------
4 affected packages on all of their supported architectures.

Description
===========
KPDF includes code from xpdf that is vulnerable to an integer overflow
in the StreamPredictor::StreamPredictor() function.
Impact
======
A remote attacker could entice a user to open a specially crafted PDF
file in KWord or KPDF that would exploit the integer overflow to cause
a stack-based buffer overflow in the StreamPredictor::getNextLine()
function, possibly resulting in the execution of arbitrary code with
the privileges of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All KOffice users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/koffice-1.6.3-r1"
All KWord users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r1"
All KDE Graphics Libraries users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r1"
All KPDF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r1"
