The kdegraphics packages contain applications for the K Desktop Environment including kpdf, a pdf file viewer.
Several flaws were discovered in kpdf. An attacker could construct a carefully crafted PDF file that could cause kpdf to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project assigned the names CVE-2005-3191, CVE-2005-3192, and CVE-2005-3193 to these issues.
Users of kpdf should upgrade to these updated packages, which contain a backported patch to resolve these issues.
