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.
Note this issue does not affect Red Hat Enterprise Linux 3 or 2.1.
Users of kpdf should upgrade to these updated packages, which contains a backported patch to resolve this issue.
