Critical: kdegraphics security update
Security Advisory: Critical
Updated kdegraphics packages that fix two security issues are now available
for Red Hat Enterprise Linux 5.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
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.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
