Synopsis
========
KPdf and KOffice both include vulnerable Xpdf code to handle PDF files,
making them vulnerable to the execution of arbitrary code.
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-r2 >= 1.3.5-r2
2 kde-base/kdegraphics < 3.3.2-r2 >= 3.3.2-r2
*>= 3.2.3-r4
-------------------------------------------------------------------
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 a new stack overflow, as described in GLSA 200501-28.
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 application.
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
All KOffice users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-office/koffice
