1.106.  kdegraphics

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.

Updated kdegraphics packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kdegraphics packages contain applications for the K Desktop Environment, including KPDF, a viewer for Portable Document Format (PDF) files.

Multiple integer overflow flaws were found in KPDF's JBIG2 decoder. An attacker could create a malicious PDF file that would cause KPDF to crash or, potentially, execute arbitrary code when opened. (CVE-2009-0147, CVE-2009-1179)

Multiple buffer overflow flaws were found in KPDF's JBIG2 decoder. An attacker could create a malicious PDF file that would cause KPDF to crash or, potentially, execute arbitrary code when opened. (CVE-2009-0146, CVE-2009-1182)

Multiple flaws were found in KPDF's JBIG2 decoder that could lead to the freeing of arbitrary memory. An attacker could create a malicious PDF file that would cause KPDF to crash or, potentially, execute arbitrary code when opened. (CVE-2009-0166, CVE-2009-1180)

Multiple input validation flaws were found in KPDF's JBIG2 decoder. An attacker could create a malicious PDF file that would cause KPDF to crash or, potentially, execute arbitrary code when opened. (CVE-2009-0800)

Multiple denial of service flaws were found in KPDF's JBIG2 decoder. An attacker could create a malicious PDF that would cause KPDF to crash when opened. (CVE-2009-0799, CVE-2009-1181, CVE-2009-1183)

Red Hat would like to thank Braden Thomas and Drew Yao of the Apple Product Security team, and Will Dormann of the CERT/CC for responsibly reporting these flaws.

Users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
