Synopsis
========

KPdf and KOffice both include vulnerable Xpdf code to handle PDF files,
making them vulnerable to the execution of arbitrary code if a user is
enticed to view a malicious PDF file.

Background
==========

KPdf is a KDE-based PDF viewer included in the kdegraphics package.
KOffice is an integrated office suite for KDE.

Affected packages
=================

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

KPdf and KOffice both include Xpdf code to handle PDF files. Xpdf is
vulnerable to multiple new integer overflows, as described in GLSA
200412-24.

Impact
======

An attacker could entice a user to open a specially-crafted PDF file,
potentially resulting in the 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 KPdf users should upgrade to the latest version of kdegraphics:

    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/kdegraphics

Note: There is currently no fixed stable 3.3.x version for sparc.

All KOffice users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose app-office/koffice
