Description Jan Lieskovsky 2009-06-18 08:36:59 EDT
Null-pointer dereference due to an array index error 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).
