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.

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"
