Updated kdegraphics packages that resolve a security issue in kpdf are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The kdegraphics packages contain applications for the K Desktop Environment
including kpdf, a pdf file viewer.

A flaw was discovered in kpdf. An attacker could construct a carefully
crafted PDF file that would cause kpdf to consume all available disk space
in /tmp when opened. The Common Vulnerabilities and Exposures project
assigned the name CAN-2005-2097 to this issue.
