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
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/koffice < 1.3.5-r1 >= 1.3.5-r1
2 kde-base/kdegraphics < 3.3.2-r1 >= 3.3.2-r1
*>= 3.2.3-r3
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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
