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"
