Summary

The kdegraphics packages contain applications for the K Desktop Environment (KDE). Scalable Vector Graphics (SVG) is an XML-based language to describe vector images. KSVG is a framework aimed at implementing the latest W3C SVG specifications.
A use-after-free flaw was found in the KDE KSVG animation element implementation. A remote attacker could create a specially-crafted SVG image, which once opened by an unsuspecting user, could cause a denial of service (Konqueror crash) or, potentially, execute arbitrary code with the privileges of the user running Konqueror. (CVE-2009-1709)
A NULL pointer dereference flaw was found in the KDE, KSVG SVGList interface implementation. A remote attacker could create a specially-crafted SVG image, which once opened by an unsuspecting user, would cause memory corruption, leading to a denial of service (Konqueror crash). (CVE-2009-0945)
All users of kdegraphics should upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect.
