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

KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered
that the Xpdf code is vulnerable a heap based overflow in the splash
rasterizer engine.

Impact
======

An attacker could entice a user to open a specially crafted PDF file
with Kpdf, 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 kdegraphics users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r4"

All Kpdf users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r4"
