Synopsis
========

GPdf, KPDF and KOffice all include vulnerable xpdf code to handle PDF
files, making them vulnerable to execution of arbitrary code upon
viewing a malicious PDF file.

Background
==========

GPdf is a Gnome-based PDF viewer. KPDF, part of the kdegraphics
package, is a KDE-based PDF viewer. KOffice is an integrated office
suite for KDE.

Description
===========

GPdf, KPDF and KOffice all include xpdf code to handle PDF files. xpdf
is vulnerable to multiple integer overflows, as described in GLSA
200410-20.

Impact
======

An attacker could entice a user to open a specially-crafted PDF file,
potentially resulting in execution of arbitrary code with the rights of
the user running the affected utility.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All GPdf users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/gpdf-0.132-r1"

All KDE users should upgrade to the latest version of kdegraphics:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.0-r1"

All KOffice users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/koffice-1.3.3-r1"
